Dude I have watched your gun videos for YEARS and I never once knew you had a guitar channel 🤣 great work!!
That’s hilarious
This guy is a gun guy and a guitar guy his wife must be an angel😂
Knowing this really helps this channel's name make a lot more sense.😂
Great video! The Fender Concert sounds amazing.
Well here I thought I was the only gun nerd with great taste in vintage and vintage style amps and guitars and basses! Like I have an all original 68 drip edge bass man with matching oversized cab and that’s my K31 Swiss. And I use a 92 strat or 95 SG Standard though it and that’s my CZ-75! I also run my 51 Tele bass Pbass which would be the CZ variant LOL HAHAHA. I have a 1970 Bandmaster stack as my Makarov and only play my 58 tele through that which is my Mosin Nagant 91/30 that’s used only for traditional honky tonk hahaha. 60SG Custom cream with white guard gold hardware and a bigsby and three humbuckers through a Marshall plexi 100watt super lead.....you guessed it that’s my M1 Garand with my old slab side colt 1911 at my side battle combo! Everything in my life is God first then guns, guitars, amps, and custom bobber Harley Davidsons! And yes I try to involve my 9 year old daughter, siblings, parents, and grandparents as much as possible especially since my love of firearms, guitars, and Harleys comes from the last two hahaha!!!!!
Dude how have I been watching you for years and not know about this channel?
Same lmao
Same
Talk about bridging channels.
I bought the Radial ABY box with phase reversal and ISO Switches so I could play both channels. Works great and sounds huge. This is the way to get around phase issues between two channels. The reason some go out of phase is because one Channel has an extra gain stage and thus when using both together one signal is flipped. The Radial box removes this problem by sending the guitar signal into the second channel already flipped so when it exits it is in phase with the first.
Edit: for my twin reverb
I didn't expect to see you on a channel like this. I've followed iv8888 for like 10 or more years and didn't know you were a musician. Wow
New subscriber here in East Tennessee... You are an excellent guitarist. It is obvious you play a lot. You know your chords. I dig chords. I have been playing 52 years and your playing reminds me of mine. Cheers!
Go figure, I’ve watched so many iraqvet888 videos, and randomly came across this, love it, subscribed because I’m into old gear and tube amp tones. Great video Eric, and love the gear
I can't believe I just now found your guitar channel. 😳 Holy cow. I watched a ton of iv8888 videos and never knew this existed. Stoked.
For anyone thinking of doing this, you MUST read! This works great but you need to know the tricks. The 2 channels are out of phase so you need an a/b/y pedal or what I do because it’s free, although not as good as having the pedal, set bass on normal channel to your desired level and the treble to zero and set treble as desired on vibrato channel and bass to zero. Start there and make small adjustments but always keeping the eq mismatch between channels. Get the best tone you can, then flip flop the settings between channels and see if the tone is better. If not put them back and your done. The channels are out of phase and mismatching the EQ helps thicken the tone. It’s the key to getting the great tone without an a/b/y pedal.
If you bridge the channels and you're having a phase issue, all you have to do is make a special patch cable. You want one end of the cable to be wired normally, and the other end of the cable you just switch the wires. That will clear up any phase issues.
then you have a reverse phased pickup entering a out of phase circut.
@@mriosgto correct
So his advice is bad??
@@ernestpetu5691 I never said that, I was only giving alternate good advice.
@@mark5150ty would that advice work for an ac30c2?
Eric, you can’t just bridge channels. All reverb amps, unless internally modded, will be out of phase. The phase issue is caused by the reverb side having an additional preamp stage.
Any time you go through a tube and the signal goes through the plate/anode(standard amp circuitry), the sine wave is the opposite of the signal coming in at the grid. The opposite is true if it goes through the cathode, the signal leaves the same as input by the grid. Btw, this is how a cathodyne phase inverter works(5E3, Princeton Reverb, etc)
Most Fender amps without reverb can be jumpered(successfully), except the Blonde/Black/Silver Bassman. The 6G6,AA and AB Bassman has two preamps on the Normal and three on the Bass, like all reverb amps.
*You are canceling out your signal if you jumper amps with different amounts of gain stages per channel*.
Edit for clarification- Even numbers or multiples of even number of stages will not work with odd numbers of stages. Example - A 4 preamp stage channel can be successfully jumped to a 2 preamp stage channel.
Than what should you do? Is there a way to do so? How about a 1972 Fender Twin reverb,or 1965 Fender Bassman?
@Michael Craig There are certain pedals that when you use them, they invert your signal, one of them being the Dynacomp. If you use an ABY box to send two signals to each channel, one clean and one with the Dynacomp, you should end up the two channels in-phase.
I know when,he kept,sayimg,like the bass man I was like that is one,of,the few,you cant bridge successfully without a mod,or,like,you said giving,the normal,1 more,flip before hitting,power amp,
I bridged mine, my guitar is in the normal channel, with it bridged into the second input of the vibrato channel. And it sounds super fat and clear
AB165 Bassman is in phase
Noticed Shakira's Mongoose tour guitarists using old vintage Fender Amps and sound great.
It has to do with gain stages. If both channels go through an even number of sides of preamp tubes they will be in phase. If both channels go through an odd number of triodes they will be in phase. However, if one goes through an even number and the other channel goes through an odd number, they will be out of phase and will need to be fixed by adding a pedal (like many aby pedals) with a phase switch on it to fix the signals so they complement each other instead of cancel common frequencies. Cheers.
Talk about a straight shooter.
Love your videos, Eric!😊
The bridged phase issue occurs only on reverb amps, Deluxe Reverb, Super reverb, Bandmaster reverb, etc. These amps have the extra 12ax7 reverb mix tube on the vibrato channel, that inverts the phase. The older Fender blackface (Reverb) amps are exactly the same, can't do it! All other amps without reverb are same phase, ie: Deluxe, (no verb) Tremolux, Bandmaster, Bassman, Concert amp in the video. The patched channels sum together, and sound good.
In the 80s I bought a blackface tremolux head. I can't even remember why I jumped the channels. I just did it. It sounded like a marshall. But of course like everything I traded it.
"Where is that confounded bridge".
Are you sure that only channel 2 has the presence control? Usually the presence knob controls the negative feedback circuit in the power amp (not the preamp) and should affect both channels.
If your Fender amp has reverb, the channels do not sum. But without reverb, the channels do sum in phase. The reason is the extra 12ax7 mix tube (verb return) inverts the phase on the vibrato channel. The older blackface models are no different, if it has verb, the channels are out of phase. For example: the Deluxe amp can be bridged, the Deluxe Reverb can not... you'll have phase problems and reduced gain.
Killer video. I'm amazed how you keep up with bothchannels. It's much appreciated :)
On models that are out of phase, if you do the Rob Robinett Reverb/+Vibrato to both channels MOD it enables you to do the jumper in phase,.. use his MOD not the 68 RI mod.
With some amps the phasing issue disappears if you turn the bass down on the other channel and the treble up on the other, and vice versa.
Thanks for this info.. might try my old MusicMan amp to see how it goes 🤙🏽
What the heck?! Dude - you're a guitarist! Super cool - I know you from your other channel (bang, bang!)
The tone you've got at 5:10 sounds killer man. I found you through your gun channel, super awesome that you're into music too!
Yeah this amp came from Frank Varilli's collection and hes a know amp tweaker. He really dials these things in right.
Thanks, man, muy buen aporte!! Voy rápido a probarlo.
Could you daisychain into other amps this way?
If you want less vibrato and you just turned down the "intensity" knob (unbridged), how is that different from bridging and turning up the dry channel?
The whole time I was thinking the same thing, if you want the vibrato to be less intense... then just turn down the intensity?!
It's not,about the that if you like the intensity the way it is you can,control the volume of,it its not,the same,thing at all if you want it in your face loud and I, the for,front then,dont worry about it if you want it subdued then it works,great still,have that strong intensity and,speed as,you like but not,dominating,the overall,sound
Exactly. Thank you! This is just a vid about over complimicationizating things.
What kind of guitar players don't like experimenting with new tonal ideas & finding unique guitar sounds? I guess some of yall just like the old plug n play sounds
Ive been bridging my 1970 deluxe reverb reissue and it sounds good to my ear, is that too new of an amp to be doing that with?
Great stuff here. I never thought about the amp transformer having this type of affect. And what a cool wall of guitars :-) nice job!
Hey your one of my gun guys I like to watch I didnt know you played too! I just found this. Im all about the 3 G’s too, God Guns Guitars and one more for good luck, gardens…..
Does channel jumpering work with the Custom Vibrolux Reverb? I’ve seen that amp on this channel before
What about a Music Man 1977 HD130 2x12. I heard that Cub Koda from Brownsville station used to use a y cord and plug into two Fender twin reverbs! Nice MM guitar in the background I would like to find a black one!
I've been subbed to the iraqvet888 channel for years and didn't know this channel existed.
what about a super reverb without he master volume 1971 before they added the master vol. those can be bridged without phase issues right?
phase issues are remedied by a ABY pedal with phase reversal switch (most blackface reverb amps have out of phase channels - ie .not a 68 and under :(
Awesome Gun Gripes Eric!!!!
Is there a way to connect two amplifiers together wirelessly?
10:13 bridging multiple amplifiers
Holy shit…I didn’t know you were a guitar player too. SUBSCRIBED
When your rig sounds so good you forget you are doing a video and just play....
hey-your the gun dude right? fuck yeah bro!!!
Your right about phasing but it all depends on,how many stages it goes through before hitting the power amp,section if one has more or less stages than the other channel then it will,not work ie. The baseman with out mods will not work because the bass input goes through 1 more,gain,stage than the normal,channel really thats all,it comes,down,to everything else in,yoir video is correct and,honestly what is the purpose to bridging a baseman anyway I suppose the deep and the bright would,be able to,play with that some,I suppose but there are no effects to manipulate
Music Man amp safe to try bridging on?
wait howd you get reverb on an amp without reverb ? haha ? the trem quiet is reverby ?
Will this work on my 1960 fender Vibrasonic? I don’t have reverb on that amp.
It’s not going to hurt it to try it. You’ll know it’s out of phase it will sound really nasally and shrill.
What's that natural wood guitar on the right? With the humbuckers
you like the a minor huh nice blues :)
I was watching the intro and was like, wait is that iraqwarveteren8888 or whatever the channel was. 😆
what confuses me about this is ... I have a hard and fast rule where output goes into input or something is going to get hot very quickly. In my mind I don't see any signal coming out of an input that would go into a second input. But hey ... if it works I can ignore the rules. Great video ... thanks!
jumping back into your other channel is not so impressive as going to another amp IMHO fender marshall make the best mates , try it you will be impressed
laney AOR will not do that.
It's more like using a Y guitar cord to drive both channels at the same time, not like the signal is going in and back out. Just driving both channels simultaneously.
How the heck did you tear up your guitar like that?
Awesome... we have at least two things in common. I bridge in a super lead as well as 5E3. Both are older than sh*t.
Subbed 👍
OK - let me add my 2 cents. First, the idea of running a patch cable between the two channels gives me the heebie-jeebies. Some amps I guess wont mind but dear God if you try that with some older gear you'll be on eBay looking for new driver tubes. THe problem is you are out of phase. A patch cable will attach + to + and - to - and that is NOT proper bridging. THe idea in a amp bridge is you take + to the cabinet from one amp (or channel) and the - from the second channel. Then you cross the - from channel A to the + of channel B. This is almost always done with identical mono amps (or channels if you amp has 'em).
I was blessed and cursed by growing up in Colonia NJ in the 70's. Cursed because they now say all us CHS graduates are getting brain cancer (check the news). Blessed because I studied amp building with a neighbor named Ken Fisher (and if you don't know that name, shame on you - Google it). We played a LOT with bridged amps because Ken was always squeezing wattage out of KT-88's - and bridging DOES combine the wattage of both channels. I recently worked on a MESA Boogie Bass Prodigy (sold it on Reverb, look it up, item # was 77534315) and it had a switch right up front to do exactly when Ken was doing decades ago.
TAKE MY ADVICE - if you want to do this, have someone make you the right cables to do it. Again - channel A + to speaker cab, channel B - to cabinet, and A - tied to B + (be careful saying B+ around amp builders, it means something shockingly different).
Im still a little unclear what exactly the reason for doing this is? Are you just able to broaden your tonal pallet? I have three fender tube amps and have never tried this but recall hearing of it. I mean I love the sound of them as is but maybe I shoudl try this. Seems like it could damage the amp though...or shock me :(
It depends on,which amp,you have there is,no danger in bridging it will,nkt increase any shock hazzard you will know pretty quickly if your amp,is abke,to be bridged with success the reason is just as he said it gives you more,control over say the intensity and,speed set them,hiw you like and,then,you can,control the volume,of them,that is the reason for,the bridge volume,control of the reverb and tremelo do you want, it to be in your face or,subdued thats the control you get from,bridging the reason it doesnt,work,on some,amps is stages of,gain if one,channel,has 1 more stages than the other thats when,you,will get the phasing issue nothing to be fearful,of just wont,sound,good you'll know,right away try it oit though I think you'll like your amps,even,more it does add an element of,simething,new,to,mess with and,if your a,guitar guy most,likely you like something,new,to,keep you stimulated
to keep,improving,this is just another thing,that I think,you'll get a kick,out of and,may imspire,you to a new level
I might purchase a 1967 Fender Bassman, however I live in a flat so can't turn it up to get that good sound. If i crank one channel and put it into the other but lower the output would I achieve that good cranked tube amp sound but at a lower volume?
No it’s still going to be loud as hell. Lol
Also,he,kept sayimg,the bass man it actually is one,od the amps,not able,to,bridge with out mods done,to,it the bass input goes,through 1 more gain,stage than,the normal,does such will give you the phasing,issue he is speaking,about
@@JethroBoDean
You should make a video.
@@JethroBoDean depends on the circuit. The AB165 bassman, which is most black panel bassman heads and all SF until May of 68, are in phase with each other. Cheers.
@@kosmicwizard jump to a old Marshall for the best sounding pair try each one first they blend perfectly, try it.
I have a 71 pro reverb silverface, think this could work?
No. Read my other comment.
Like I said in the video you’ll likely have phase issues because of the Reverb
I have a 1968 band master without a reverb unit. Would that work?
Wow, hi Iraqveteran8888
Can I bridge my 1974 bandmaster
On some amps this works and some it does not. Plug in the jumper cables and if you can drive both channels with it's individual volume control then your in business. If it doesn't then your SOL Simple as that.
Exactly where in the video do you say how it's not in the first 5 minutes which is ridiculous for a video titled "How To"
look at the thumbnail of the video and use your imagination.
YOUR Tone Is Always Too Treble For My Taste But You Are A Very Good player. Maybe in a band setting all that treble is good. I did like finding out about bridge the two channels and multiple amps
I have high frequency hearing loss so that’s probably not helping...🤣
Its actually most likely his mic placement. Also that tone will cut through q mix
I’m thinking of picking up a Royer 121. It’s an expensive mic but I feel like the frequency response on the SM-58 and Sennhesier 609 may not be perfect for this application. For live miking applications they are ideal, but for this I’m going to look into upgrading
Wait… Eric? WTF MAN? I watch you for gun meltdown Videos! Not amp advice! 😂😂😂
👍🔥🎸🦅
The fuck? The gun tuber also plays guitar? Does everyone I know do both guns and guitars?
