You have repeatedly proven to me that speakers and cabinets are such huge part of any amplifiers sound. Makes picking a speaker/cab even more daunting.
+Nicholas de la Rua Thanks! :-)
I've found the pairing makes all the difference. I generally hate G12T75s, I tried them with a 50 watt JCM 900 SL-X head, an Ampeg VL1002, Bugera 1990 and even a JCM900 High Gain Dual Reverb and never liked them. However, when I plugged a JCM2000 DSL head into them, I really liked them (so I kept the head). It's really not an easy task!!!
Shows you gotta do some comparisons to find what you really like.
Nemo Alicunde that can be very difficult when time and money is an issue. I'm about to build my cabinet out of my old combo, so not much choice in cab per day, but speakers... so many choices.
I've been down the speaker wormhole, don't do it. You will find something you like about EVERY speaker you try, whether it's the low end of the G12-75 or the agressive mids of the Greenbacks, or the clarity of the G12H or the sweetness of the G12-65. It's impossible to choose a cab that covers it all, and who can store eight 4x12s! I'm currently running 2x G12-65 in a 2x12 Marshall cab and although I know what other speakers have to offer, I have to just build my rig around that cab and EQ accordingly. Having said that, I do have another 2x12 with Greenbacks in, for when the mood takes me! lol
You should sell t-shirts that say, "so...let's go". I'd buy one. (Black Large, please)
Cheers Michael ;-)
I’d actually buy one too
I'd buy one!
Or lets šek out!
JMP + G12M25 is such a great combination. The 70's heads always get overshadowed by the more popular 800's or plexi's, but they just sound so good.
+David Gossett yeah, that's the ultimate rock tone to me :-)
The 2204 JMP with 25w Greenbacks wins every time!
Best amp ever made! 👍
+Flametopology Yeah it's my go-to Marshall :-)
Johan Segeborn
Same for me as well!👍
+ Flametopology 👍
Agreed.
Nah the JMP100 2203 is better. More neighbors annoyed = win!
That 900 sounds awesome through the vintage cab!
Thanks! :-)
i had one back in the 90s and man it sounded like heaven...back the gain and here you go...really good with pedals ...i used a ts5 sound tank tube screamer and ..a guy on a gig ask me to exchange with his late 70, 100 watts head and i refused ...
@@sttyves yeah,bullshit you did.nice fantasy,go back to sleep liar....no one trades a $5000 superlead for a jcm900 unless its a drug fueled ,delusional dream.straighten up
trillrif axegrindor I would take the 900 with the vintage cab, the 900 is good value.
The JCM900 to me is one of the most underrated Marshalls. I love it and the only thing you should pay attention to is a proper treble adjustment. It has a lot treble. One second point is that this amp is made to sound good in a band context rather than in your living room. It is a fantastic live amp.
great demo Johan, I have a 2203 & 4100 and G12m65's in my 1960A cab & G12T75's in the B cab. The 900 loves both especially at high volume however for low volume the G12M65's are a little nicer.
The problem with most people that dislike the 900 is they play them with the master vol low with full gain, these amps need to be turned up to get the power section working....they become a different animal then
That 900 sounds KILLER with the greenback cab! Thanks for showing this - I am getting a 900 because of this video!. Thanks, Johan! "let's go"
I’m convinced that the 900 was the last classic Marshall head. So heavy. Yet crisp like an 800.
I have a 1995 just like this one and I run it with a Friedman Buxom Boost pedal through a pair of Vintage 30 & G12T-75`s and it sounds pretty sweet. I play either my Korean Epiphone Les Paul Standard with Duncan 59's or my Korean Epiphone SG with a Super Distortion. I'm amp came loaded with Mesa 6L6 but i think I'm going to put in some JJ 5581 because I've seen a few videos and the 5581 tube seems to be closer to the warm EL34.
I agree. Last of the real Marshalls. And the cab DEFINITELY changes everything. Love my 9 through a Mesa cab.
@@mattreichenberg309 I wouldn’t say that. The DSLs are legit. And I’m also a 2204 (5881’s) Jose’d Plexi owner. It surprises me more every time so play it.
Now the MX412 OTOH, does it zero justice. But through my Bogner straight 412 (V30s/C90s) and my 80’s Randall 412 (WGS GBs/Reapers), it slays. I don’t even play my 5150iii EL34 anymore after getting the DSL 😂
Johan, you are simply a beast. You get awesome tone out of everything you touch. Truly a gifted individual. Love your work!!
+Noeffnwaypal Thanks, you make my day :-)
Johan Segeborn I agree, you my friend make everything sound good. I liked the JMP just a tiny bit more! Rock on🎸🤘
The JCM900 has high gain, i used to have one like this many years ago with a 1960A, maybe about time to buy a JCM900 again.. both these amps sounds awesome and the JMP is great for rock n roll.. great playing..
+HearGear Thanks, glad to hear it!
actually,no it doesn't really have high gain but it does have a solid state rectifier that gives a little more brittle sound.
the jcm900 sl-x has fairly high gain though but i definitely prefer the plexi or the jcm 800 variants
I normally put your videos on in the background while I clean or exercise. I was cleaning and I sprinted back to the TV when I heard the tone at 1:58. Sometimes I think I like the JMP just because they're semi-rare here in America, but even when I don't realize what I'm hearing I think "oh my god, that tone is amazing", then find out later it was a JMP.
Thank you so much for your channel, Johan! It's educational, entertaining, and helped me find out exactly what I need for the tone in my head. Definitely my favorite channel on CZcams for years!
+Caleb Neff Thanks my friend, that's so good to hear!
That 900 shines throught the checkerboard cab!
Great demo Johan
Great video. You are putting out some real nice content for us Marshall lovers! Thank you.
It's proven that the cab has more of an influence on the final sound than the cab!! Btw, that epi is stock?? Did you replace the pics?
+YouTalk TV It's completely stock actually. Surprisingly good.
It's awesome sounding!! and looking too! I actually have that same guitar but changed the pick ups for the Pearly Gates by Seymour Duncan....Let me look up a clip and I'll uploaded it. I actually changed the bridge and some other electronic stuff my guitar tech recommended
"It's proven that the cab has more of an influence on the final sound than the cab!!"
here is your quote,what exactly are you trying to say?
You know what he's trying to say lol
no,i dont actually.i think that's why i wrote it
Johan, it all sounds good to me. This just proves it's the player, not the gear.
I just bought a JCM900 model 4100 dual reverb, partly because of you and partly because it was cheap - around $380. I had a JCM900 of some kind many years ago,
which I didn´t like at all, but now I try again. It has loads of opamps inside, and some of them sits directly in the preamp signal path, but then again a lot of the good
overdrive pedals have them too. It is the FET based TL07x series, which sounds good in pedals. It will be used with a 4x12" Chinese V30 loaded Harley Benton cab,
bought second hand for around $230. A system that has been quite easy on the wallet :-) Those cabs are pretty well made, with no particle board and with metal
handles, and they are cheaper than buying the speakers chassis only. Bonusinfo: They can also be had as 2x12", and the size fits a large Marshall head. Downsides are:
A lot less attitude and street credit, and the Tolex is more sensible.
I remember being so excited when i bought my brand new 900 single 12 combo. Until I got home and plugged it in. Thin and raspy sounding overdrive. Then I put my well broken in Vintage 30. There it was. Thick rich overdrive. I sold that amp and bought an 800 later and never regretted it. The 900 was always more of a one trick pony for me, where the 800 just always seemed to sound good no matter what the settings. Thanks again for the comparison and keep up the good work.
+grizdeluxe Thanks, I will :-)
Extremely evident here that the speakers are as equally important as the amp! When played through the greenback loaded cab, both amps sounded better than when played through the t75's. I would love to hear a comparison of Vintage 30's next to those greenbacks.
+Joseph C Thanks, we can do that too!
Johan, can you please line up that test. Would be great to hear the T75's against the greenbacks (G12M25's) & the vintage 30's through the same head.
Through the 4 X12's.
Great video. Its amazing how similar those two amps sound through the same speakers. I mean there is an obvious difference in gain but the Marshall tone is still there. Its also pretty cool how different those two speakers sound :).
+Ryan Bianchi Thanks, yeah it would be interesting to mix them
Re-tubed my 900 with Tesla JJ's and now run the A channel a little dirty with a Rockman Sustainor . WOW ! Like all your Marshall Videos ...Love the Goasting sounds .
I like them both, for different reasons.
+Patrick Gauthier Thanks man
Please keep the videos coming.
Thank you for all the riffs, the enthusiasm and dedication you are a inspiration by means of sharing.
You keep this alive brother.
I have 2 Jcm 900 4100s 100w don"t know what years and I really like them but, I do find they are alot better amp on a v30 cab.Johan your videos are awesome I'm glad you make these such a wealth of knowledge.Cheers!!!
+darthbeviz79 Thanks, good to hear that. Cheers!
I owned one 10 years ago.. was not happy. I own one today asecond time. As soon as i got it, i sold my v30 for greenbacks. Waaaay better. Nothing to compare.. the v30 are too harsh for the 900 that is already a shinny amp.
Wow!!!
I've always been told that the 900 didn't sound that good . But That sounded AWESOME!!!.
Btw you put a lot of work into your videos , much respect to you sir!
People crap on the 900 all the time. I think at this point, it’s just something people say without any merit. It’s a fine amp, as Johan has shown us in this video. Not necessarily my cup of tea, but it’s sounds far from bad. I wouldn’t be sad if I owned one. Lol
Compared the 425a cab and 1960a w/G12T-75's on my 2466 Vintage Modern. Both cabs are so close but the more you play, the more you can hear the beauty of the G12C's and how they pair with the VM amp. great comparison videos Johan .. always makes me remember how important each component is.
+Tricko Thanks! The G12Cs are indeed great!
Man I'd love to be in a band with you! You are one smoking guitar player. hats off
+whip's cheap guitars Thanks :-) You make my day!
Glad to hear you Johan haven't heard you in a while good to hear you hear your kicking on these Marshalls kind of lost you there for a while good to see you and good to hear you
0:52 JCM900 1:00 JMP
The geetar counts as much as the speaks, regardless the make quality is a must. Love both amps they'll rattle nards, thanks for posting!
sounded like...marshalls.
+STEVE LEITNER Thanks! Can't go wrong with a Marshall ;-)
Unless it's its a JCM 900 (save for the SL-X)
They all have their own charm and personality. I also love the way Johan says "Hoff Stacks". Tak!
You ever try a JCM 900 MKIII?
There are differences in the mids between heads and between cabs but they sound more alike than different based on what is represented here. JMP 50w MV is my favourite of all Marshalls (especially the 2x12 combo version) but that 900 DR does sound very respectable here.
1:38 Wicked pinch-harmonic. And the first solo on the JMC was damn tasty to boot. Your vibrato is otherworldly dude.
I liked the mismatch...each seemed to sonically benefit from the swap...though I own a JCM900 Dual Reverb 4100 the JMP through the JCM cab sounded GrEaT!
Now I need to go back through your speaker comparison videos again......AHHHHHHH!!!
+Chris Mitlyng hahaha! Sorry about that ;-)
I loved your MG100 video so much. Please put that MG100 head through the cab with the G12T-75's. Or better yet have a shoot out of cabs with the MG head. Truly thank you for the superbly high quality content Johan!
+Alastair Tilley Thanks Alastair! Glad to hear it!
Loved the video! I think each amp sounded best with its matched cab. They both kinda got little muddy with the switched cabs.
Also, the description says JCM800 instead of JCM900, figured I should let you know.
cool comparison Johan and as usual the results change our beliefs...... Congratulations.....
+PureToneAmps Thanks man :-)
Both heads sound better through the older cabinet. No surprise there. The G12T75 is a hideous speaker. I never understood how it shipped in Marshall's flagship cabinets for so many years. Even through the vintage cab the JCM900 can't hang with the JMP. Great video as always, Johan.
I can't believe the JMP has as much gain as the 900? Awesome as always Johan.
+Peter Cross Thanks Peter, the 900 actually has a lot more gain but for these riffs they have both enough gain. Cheers
Wow... I didn't know a 4100 could sound so good! I owned one for a few months and really grew to dislike the feel and sound. Had I known I just needed a new cab I probably would have kept it! Luckily I found a Slash 2555 Jubilee, matches it with a quality old van and fell in love. It doesn't get any better for me.
Those Greenbacks definitely do the business. The JMP is in front of the JCM900 for me too. Old school crunch!
+Chris ACT Thanks, yeah the old Greenbacks are the only piece of gear I couldn't do without.
How much difference can be attributed to the cab builds? Do you think it all comes-down to the speakers?
+djdurkadurka The Cab itself contributes surprisingly much too. But the speakers are the most important
Hi Johan. This is Luis from PedalPalFx... first of all here at the shop we are big fans of your demos in youtube and an important reference regarding Marshall tones for us, that being said...Would you be interested to make a review of a pedal effect based on the JCM800?... It would be a great privilege for us, please let as know... hope you read this comment... Best Regards, Luis.
+PedalPalFx Hi Luis! Great to hear that you like the Channel! :-) I'd love to demo the pedal. I liked how it sounded in your clip. Cheers
Excellent!!! thanks alot for this opportunity!!! we are going to send you a private message at the link in you channel in order to keep in touch and send you a pedal... Best Regards.
A friend of mine has one of these '70s 50-watters with matching cab and it too sounds amazing - great midrange and so much character, very "electric" if that makes sense! Needless to say I am quite jealous. :) Love your videos - always great playing and miking technique.
Celestion G12M are awsome!!!
+Aldo Gorjon Greatest speaker ever! :-)
Is there a typo in the description? The High Gain Dual Reverb is a JCM900 series amp right (as of this writing it says JCM800)?
At any rate, I came across an old mail order catalog the other day from the late '70s. JMP 50 watt heads were $449 US (100 watt heads were $499 US), 1960 cabinets were about the same ($450US) and 1982 cabinets a little more. I still kick myself for not buying a 50 watt half-stack back then!
+BB2009LZ Thanks for pointing it out! But that's more expensive than I thought. Cheers
You need to remember that because of inflation, $450 was a lot more money back then than it is today. It would probably be something like $1500-2000 in today's money (at least according to the inflation calculator).
The jcm 100w dual reverb 4100 is just over $2000 new. It gets more expensive from there to get to the hand wired marshalls. High 2's and 3k.
Excellent demo, I had a JCM 900 in the late nineties great Amp, but the JMP wins hands down.
+John Roberts Thanks John!
I acquired a JCM 900 4100 a couple of months ago. I plugged straight in and tried channel B (the one with extra distortion via solid state clipping) and was fairly disappointed. Then I tried channel A and got things dialed in - ahhhhh ... there's that vintage Marshall tone. I run channel A with a somewhat clean tone (gain around 6.2) and use it as a pedal platform into a Marshall 1965a 4x10. Sounds great at gigs so quite happy with it. Just makes the B channel, reverb, and effects loop circuitry that I don't use overkill. Will probably build a plexi clone one day that matches the dimensions of my 4x10, mostly just for fun and to keep things simpler circuit-wise - not convinced it will actually sound better than the 900.
You made the 900 sound incredible with other speakers! The stock cab really trashes it. This is super interesting.
+Niko Pappas Thanks, yeah the greenbacks make it sound much bigger to me
impressive ! Thanks for that. you rule as always !
+lennyced31 Thanks man! :-)
The G12T-75 speakers turned that snarling JMP 2204 into a roaring JCM800 2204. Whether "snarl" or "roar" is better is really a matter of taste and how it would fit with the rest of the band.
Greenbacks for the win. The JCM sounds killer through that cab though.
I know it's a comparison and not a competition, but jmp with any cab for me. Great demo Johan
El JCM900 con esa Explorer truena poca madre... Saludo desde México, maestro.
Hello Johan, after watching this video I bought a 1977 JMP 2203 and I love it!!!! I now want to score some vintage Greenbacks, the ones you use in the video, are those model T1221?
+Rieni Otten Glad to hear it! Yeah that's a 1960A Cab with T1221 Greenbacks from 1971. Cheers
Johan Segeborn
Thanks!
Surprisingly good tone from a Dual Reverb actually.
That jmp is killer. any modern speakers you have found that come close to the vintage greenbacks?
+Dan Kiefert Thanks, The closest available today are the Heritage Greenbacks from Celestion, but they still differ quite a lot, especially in the very top end.
Dan Kiefert
Eminence makes a great green back clone called the private jack.
@@metalbeast1998 and it sucks in comparison
Couldn’t help but notice along with the Marshall gear. Say, that’s a nice Explorer you’re wielding there!
I had a JCM900 once.... Sold it and bought a Mesa Triaxis. That thing was hard to get right and needed help so I sold that and the 2:90 I had and bought a JVM210. Now all is well in the universe. At least the one in my studio haha. Was hard to track the differences on this one Johan. But I get lost quickly lol.
+Legend of the strings Thanks, I like JVM too
The jcm is more "Metallica" but the JMP sounds best imo
+Sniperfire24 Thanks! :-)
metallica was jmp
@@Shadow__Banned metallica was modded jcm800 with a mesa markiic slaved into it....fucking people repeating utter nonsense
I don't know why, but I generally dislike Marshall amps... It might just be that I WANT to dislike them because of their overwhelming prevalence, but your videos make me wonder why I don't have one yet.
+Nate Popodi Thanks Nate, I'm glad to hear that! :-)
Marshalls are like women....no 2 are exactly alike, so you just need to keep swapping until you find the right one. And then when you do, be smart enough to hang onto her!!!
do you like aerosmith?
do you like guns and roses?
do you like ac/dc?
do you like led zepplin?
do you like black sabbath?
do you like judas priest?
do you like iron maiden?
these and several 100,000s of other rock,hard rock,metal,alternative,blues,country,pop and other artists use Marshall as their primary choice of amplification,if you listened to the radio or music today,you heard a Marshall
i dont know why you would spend time on a video that is primarily a Marshall
proving ground if you do not like Marshall amplifiers,maybe you are confused?
@@trillrifaxegrindor4411 maybe he finally came around! Marshall rules !
The JMP sounds great through both cabs.I can't pick a favorite. You should use that Explorer more often.
+pedraw Thanks! :-)
Yeah, I agree: the JCM deserves to played with some V30s.... that's where it really shines.
For the Explorer: get a longer strap, man, seriously!^^
+John Doe hahaha, I'm afraid it's either look bad or sound bad for me ;-)
Yes the Speaker is the Key to the Sound 👍🏻
The 900 sounds nice and thick in my opinion, but my local guitar tech refuses to work on them anymore lol. He's in his mid 60's. I bought a '79 JCM 800 off of him and at the time he had a 900 sitting on the floor. He swore it would be his last!
He says the same thing as Brad the Guitologist here on CZcams: that the JMP is pretty much the perfect rock amp.
Holy crap, those G12M25s sound way more open and airy with both amps. Wouldn't even touch the other cab!
+EmperorSheepy I agree, one interesting thing though is that the other cab has G12T-75 speakers, which is the most sold guitar speaker in history!
When you say, most sold speaker in history, does that include OEM? It's kind of hard to believe that people would choose THAT cone over the other options out there.
2:43 Sounds like Silverchair's Frogstomp tone to me. Rumor has it he used a JCM900. I don't know what his cab was but some old comments I saw on a forum said that 10 years ago, after he switched to Soldano HotRod amps, he was using Greenback loaded cabs with them.
Based on the crunch sound of the 900 through the GBs here I suspect he always used Greenbacks.
I met the designer of Soldano amps once backstsge Gov't Mule super cool fella reminded me of the actor Jeff G. of Jurassic Park/the Fly
@@kennethjohnson6223 Very cool! I talked with Mike at length when I bought the Astroverb effects loop prototype from him in 2002. I stopped in 3 times because he let me make payments and he was very patient and interested in answering all my stupid newbie questions. A _SUPER_ nice guy, for sure!
I just fitted a speaker out jack to my boss Katana combo, the difference between the Katana speaker and the Marshall 1912 cab I have is like night and day, the boss speaker is louder and brighter, the Marshall is boomy and soft, changing speakers an cabs results in the biggest change in tone that you can make
More great tones! I'm not really coming here any more to see if there's a difference...just to hear you jam on great equipment! haha.
+Rick McCargar Thanks man, good to hear that :-)
johan..gotta be the JMP..ALL THE WAY BABY!!!!!
Such a shame they 900s get some bad rep. They can sound so good and you prove it in any videos they feature!
+Brian Forsyth Thanks, they had some bad luck with the timing, they came at the same time as 80s metal went out of fashion.
The vintage modern is also one of those "under the radar" excellent Marshall heads you can sometimes score on the cheap.
its not a shame at all,its a fucking great thing,they remain cheap because of stupidity
I've owned both a JCM900 SL-X 100w and a JMP100 '79. Both sounded great with "Blackback" style Scumbacks and Celestion Creamback reissues. The 900 is highly under-rated IMO. Only thing that freaked me out is how much lighter it was than my older Marshalls. I'm guessing transformer weight??? Not 100% sure, but heavier must be better, right? And yes, (just like speakers) glass matters. I put some decent early 80's Teslas EL34's in my SL-X and some GE 12AX7s. Sounded legit to my ears.
Checker the cab with a slx or Dual Reverb 50W and it’s damn good. Nothing beats that JMP sound though.
I want a natural finish explorer. Have a red wine one but the natural looks cooler imo. But I wouldnt have the guitar that high up... Nice video! A true rocking sound!!!
didnt understand ...this means if i connect a jcm900 to a vintage cab it will sound like jmp???
+silver stone Yeah, close enough at any rate :-)
What about the 65s found in early jcm800 cabs though?
Johan, would you be able to do a video on your guitars and amps? You've got some of the best guitar porn on youtube!
I've been suprised you've not had a Silver Jubilee video. I have the 2555x 100w reissue, with a Marshall 1960A with Vintage 30's and have wondered what it would sound like if I could play it gunned to the levels you are able to do. Stupidly it's my bedroom rig!
+Dan Allnatt That's a brutal bedroom rig :-) I have a couple of Silver videos actually

@@JohanSegebornis the only real anda true Marshall enthusiast,you should take over Marshall,you should be come Marshall CEO and bring Marshall back to their origin.
very unusable,muddy weak tone at bedroom levels.a modelling amp would unfortunately sound better
Freaking Awesome demo!!! Hey man can you do this again and maybe use the Jcm900 Mark lll and a 2203 - 2204 head? That's a comparison ive ran through my head for years and never heard live! Thanks for the killer demos dude!!!
You play the 900 on clean Channel A or on the high gain B channel?
I own one today and the A channel is really as good as i found the B channel really bad... harsh and mid scooped..
Some sort of dual side amp. Vintage/modern insome ways... A for acdc, b for mettalica !
I say that use both mixed at once and you’re set . Perfect blend
Back in 1992 i bought the Valvestate VS100 head when they first came out because i couldn't afford a full tube Marshall. That being said, i swear by that head to this day. Was able to get nice cleans, decent crunch and a very good classic rock/ metal tone depending on how the contour, midrange and treble knobs were adjusted. And using a stock Fender MIM SSS Strat and a Marshall 4X10 cab, i might add. Surprisingly good sound even though a full tube amp is the way to go. Johan, obviously you are a Marshall fanatic and i imagine you must have tried out this head at some point and i would like to know your comments. Thank you!
I’ve actually done a bunch of Valvestate Marshalls here on the channel and have liked them all. Cheers
Johan...i got a 900 4102 50/100 watt combo. Will the Celestion Green Backs work safely on this amp? I know they are rated at 25 watts. If not what would be a 2nd choice?
I saw a demo from Spector Sound studios where they did an expensive head with cheap speakers and an inexpensive head with an expensive cab and the cheaper head sounded way better because the speaker's.
Why do you compare them with Volume at 10? I have a 1977 50W and if I put it higher than 5 I believe I will incur death threats, both at home and at gigs; it is just so so loud. I would be interested if you can answer a question. Can you get about the same level of distortion using a circa 1974 50W head with two channels as with a 1977 JMP that has a master vol and pre-amp? The 1974 has no preamp and I am interested in achieving about the same level of distortion at Volume set at about 3 or so, certainly not more than 5.
Black cabinet with JCM900 is too dark sounding for leads but does heavy riffs well. The JMP with the other cabinet is perfect for leads.
Another great video! It would be nice to see a decibel meter in these videos. Thanks!
I have used many cabs but in my opinion the Marshall JCM900 Lead 1960b with GT-75 is the best sounding cab.
+Albee213 Thanks, to me it's the best cab for thrash metal.
Hi Johan.
Can you please put notes on the video? It's really hard to tell which configuration is what. And the sound are sweat, but I can't tell.
Cheers
Put 2 greenbacks in the top and 2 t75's in the bottom of a 4x12 and every Marshall sounds amazing.
i don't like a lot of marshals but that last one kicks ass. i wanted you to play some sabbath soooooo bad
+Bo Huggabee Thanks Bo! I always wanna play Sabbath! \m/
Tune in next week when Johan will plug into a watermelon and still make it sound like a 1/2 stack.
This just made me want both amps more really...
Thanks Scott! :-) I’m glad to hear that
Excellent as always!
And for one more time came in front the importance of speaker and cab!
I will like to ask you if jcm 900 is the hybrid preamp version, because sounds a bit like jubille, (one of the most overrated amps ever, in my opinion.).
Thanks!
+Sceptic T Thanks, yeah it's good diods as well as tubes on the preamp. Cheers
I've just bought a 77 jmp 2204 and I'm going with 2x12 cab. 1 v30 and a creamback. Hopefully will sound great.
+Colin Robertson Good choice!
What does it do when you jump wire a Marshall head from one channel to the other? What is the purpose, and effect of that?
800 for ever!
The JMP rocks my socks off anytime =) Would you happen to have any suggestions how I could achieve the JMP sound but with living room friendly volumes? ATM I have a Blackstar 5H head (which is quite marshall-y)& Marshall 1984A 400W bass cab.
pikkuarska you need a good attenuator. thd hotplate or weber mass or the best an aracom attenuator. did not hear good rhings about the ultimate attenuator.
+pikkuarska Thanks :-) I use it the JMP both with a rather low master volume and a Weber Mass 100, into a Vintage G12M25 75Hz mounted in a 2x12 with the other slot open. The G12M has a lower efficiency than the G12H or V30 so it's quieter for the same amp output.
Also something cheap, and underrated!
A marshall guvnor 2!
You can find it dirty cheap, like 25 e used. Open it an snip out c 22 cap.
In to the midlle of the circuit you will see 2 red leds (like the ones in Christmas trees, lol). Cut them or break.
Now you have a marshally flavor semi clean pre distortion eq, but very responsive in dynamics.
Tweek the volume, gain, eq and you will be deep in marshall territory.
Thanks a lot! I will definitely check this out before throwing money for a real JMP! =)
Speakers can make or break an amp. That's why the Marshall 12w lead got a bad rap. I swapped out the original Celestions for 10" WGS Greenbacks, V30 & Jensen clones and wow! That amp is insane! It records like a dream
I really like your work here Johan but could you show us all that you can get a really good clean sound from a Marshall too.
Dern it, now I gotta start considering speakers with the heads. John, your making us all take more time in picking out our choice equipment. and consider what really will make it better. It was so much easier if not more expensive to order a slew of pedals and grind it all. JK....no exasperation here. thanks for your efforts Johan
Thanks Jed! :-)
l ll say the thanks belongs to you, You had me mad with excitement when I first hooked up with your videos. I shall always be I think, for you offer great imagination stirring video that has driven me to explore. You offer me the mysteries of the universe, I offer you a learned achievement bound my want to learn ........ Music teacher you may be....amps wise and gear. And ultimately you make free the limitations of amps once thought poor and inadequate. A true magician.... You ve bound my imagination to the laws of frequency and its ability to be altered. Bravo,
any recent cab that would sound close to the vintage one? i really love the jcm 900 with those greenbacks
