Malcolm Young had my all-time favorite guitar tone. As someone who almost only cares about rhythm guitar, his tone and play style were the absolute pinnacle. Not much gain, bright but not ice picky. The power came from his right hand, and where/how he picked/strummed. Just the perfect hard rock rhythm guitar sound.
Trust me this amp OF MINE sounded ordinary. Jason using a Les Paul with Humbuckers in the clip made it sound good. BUT with a hollow body Jet with 3.9k output Filtertron pickups it sounded woeful with no balls or volume whatsoever. Wait till part 2...
A video on the Baxandall plate fed tone stack could be interesting. Maybe we can explore a bit more about what Marshall was doing here? Please like this comment if anyone else is interested. I have been studying ACDC tone for years and I think this is closest I have ever heard.
That intro riff to Jailbreak has haunted me my whole life. It is one of the most unique tones in rock and Malcolm hasn’t exactly had it again in any other song. It’s just all bark with zero sizzle. Have never had an old Marshall or newer amp, that even when set cleaner, have no sizzle and that kind of clanging bark.
Yeah its the ultimate rhythm guitar riff played by the ultimate rhythm guitarist! When you say sizzle are you meaning that kinda fuzz/fizz when the amp starts to break up?
I actually like the sound of when the amp came in. It sounded cleaner and less fizzy or more like early ACDC which I have always preferred. this is my humble opinion. :). however I also loved the sound after Jason tackled it. I would be interested in a video explaining the differences between shared cathode and plate-fed tone stack.
I remember from the Lee Jackson Tone Talk when he told the story angus' team asked him to come and hot rod their amps. he went to sound check, listened and told them, are you crazy? no. it's perfect the way it is. holy grail right here.
You should check out the circuit for the JCM 800 version of the Super Bass, even more interesting stuff going on. They finally got serious about making the Super Bass an actual bass amp! ...(still not enough watts tho)
I know Sean , he is so passionate about the ‘Mal sound ‘ i to have an old super bass but it was Master volumed .. but still sounds very Mal :) Great stuff!
Sounds pretty good. I'm always surprised at how clean Malcolm's tone actually was, I think it was a conscious decision so that his parts would mesh with Angus's more dirty tone and both would be clearly audible. That "Rock & Roll Singer" riff was re-purposed by Billy Duffy of The Cult in a song called 'Wildflower'.
Wow, Crazy Had no Idea Marshall ever had a bax tonestack on an amp this era, really cool! Curious how it compares to the Oranges of the era considering their similarities at that point. Thanks for sharing Jason!
Might be a nice platform for a gain stage. I hadn't thought about that before with this circuit. Makes me think of a jcmb800 ish, with yet another gain stage.
JCM800 is not ONE amp, it is a broad series of amps, spanning over very different circuits: 4-input Plexi type, 2 input MV type and the real 2 channel type. More of them comes in heads, 1x12 and 2x12.
I have built around 10 tube amps from the bottom: 1987, 18w, 2204, AC30, Princeton ... and modded a lot of different amps. I have followed a lot of builds on YT, and read a lot of the tube amp books around. 2 things that make me wonder is: 1. Why don´t amps builders experiment with cathode bias ?? It is easy and sounds very good in VOX, Matchless and some older Fender amps. 2. Why don´t amp builders use the Matchless type post inverter MV ?? It puts the PI into play, and sounds very good in Matchless amps. I think about building a 50w Super Bass with cathode bias, Post PI MV and only plastic caps in the whole amp. SCR makes some 650v plastic caps that can be used for PSU caps, at reasonable prices.
The negative feedback and dissipation of cathode biasing becomes more of an issue with larger tubes which is why you usually see it used with smaller tubes, especially EL84s/6BQ5s as they only require a few volts bias. You do see it on bigger tubes from time to time though
AC/DC is a gift from God. Malcom and Angus set the standard for classic Marshall tone.

That unmodified tone sounded awesome. Need to get my hand on a 50 watt one.

Malcolm is the whole reason I ever picked up the guitar. This vid is awesome
Looking forward to the next 20 parts. 😂👍
Sean has got a diamond in the rough re this amp !!
Its better than the Hope Diamond now mate!! it'll Give your 74 Supe Bass a run for its money!!
Man that gold top sounds nice into that Marshall! Fine selection of tunes for the demo (as usual)!

Woof! That "Before" amp is dry! Can't wait to hear what you can pull off with this amp.
Great stuff, Jason! Interestingly, the modded 1992 sounds just like my ‘75 1986.
Very cool amp, I did not know Marshall built a plate fed baxandall Super Bass! Interesting circuit...

Oh my lord I already want part two
My gods that sounds amazing. Holy crap. 🤤
There it is.
that has to be the cleanest '71 i've ever seen. thought it was a reissue at first
the stock amp is sounding killer!!!!!
Here for the party 🎉
Hell yeah
Aloha and Mahalo!
Jason....you gotta get a Gretsch w/ filtertrons in yer stable of guitars....hey, Jim Moginie (Oils) used one thru his Marshall
O yes sir! That tone sound makes you want to play all night long!
Good year 1971!!
I've always felt like a lot of Malcom's early stuff didn't have a ton of distortion. Just a super-powerful sound.
Agreed. I thought the first demo was closer to Malcolms level of distortion. Just needs volume and a more aggressive right hand!
Needed an old Gretsch as well.
I’ll give you my address, you can send me one. Lol
@@HeadfirstAmps I’ll send you one 😊

100% wild flower! I've always thought that.
"re-purposed" is a very kind way to put it 🤣
Where can I find more info on that tone stack??? I built a 18w TMB. And I’ve been wanting to use it to experiment with things like this.
Far out that's THE sound right there isn't it?

Sidenote, I've put james/bax tonestacks in a few things and I've always really liked them. Especially Plate fed.
@@CausingLewis when I try it with a high impedance source in TSC it becomes very lossy and lop-sided. Is there a trick to it?
it’s definitely on the lossy side no matter what, which is why it seems to work better plate fed. Mine seems pretty flat with the controls at noon

@@qddk9545 true, but for simplicity I do believe that everyone knows which one I'm talking about
I’d love to see a schematic for this. Can’t seem to find one anywhere

Need an MY switch so onr can switch the amp in and out of the mod. Vould switch a set of relays.

The stock one sounds better...
The original is perfect, I don't understand why you have to touch it.
Two reasons. First, the owner wanted it changed. Second, it’s how I earn a living.
