What's the difference between these Marshalls?

[mmorse]

Ah, ok.

I want to see what a NMV cascaded 1959 Super Lead sounds like.

First you will have to build one because Marshall didn't. A 1959 SL has 2 channels that can be mixed. They are not cascaded. The MV Marshalls (2204/2203 etc) took the two channels and cascaded one into the other producing a one channel higher gain amp. NMV Marshalls have 2 gain stages and MV Marshalls have a third gain stage. If you want to hear a cascaded 1959, the closest you're going to get is a 2203. And they are really two different animals.

good info in this thread. Answered a lot of questions I have too. What about tube config? which amps had what power tubes?

Without going all the way back to the beginning, most Marshalls had EL34 power tubes and 12ax7 preamp tubes. At some point during the JMP era, the U.S. distributor switched the 34s out for 6550s because they could survive the trip across the pond better than 34s. Other Marshalls use 5881 power tubes.

What a coincidence. I have a box of parts arriving tomorrow courtesy of Metro Amp... And I've found a number of methods for cascading the preamp on the Metro forum and here: http://home.comcast.net/~mamp17/Misc%20 ... 0Info.html I know it probably won't sound the same as a 2203. But we'll see what happens.

I make thread!

Didn't some Superbass or Superlead use KT88?

you guys are giving me marshall gas bad

You can put 88s in any of them without too much trouble. I've had 88s in my 2204. I was just referring to what Marshall put in them. The Marshall major was a 200 watt head that I believe was fitted with 6550s but KT 88s could also be run.

Where do Jubilees fit into all of this?

Actually the 1959RR CH II is exactly this......

Jubes used the same power section of (2204s/2203s) but the preamp section was quite a bit different. They had diodes for additional OD. Basically, Marshall saw many players hitting their amps with OD pedals like tube screamers etc. This was their attempt to build the pedal into the amp itself. The earlier 2205/2210 amps did something similar. The preamp pot was a pull pot that engaged extra diodes when pulled.

Some people love Jubes, others not so much. I had a 2550 that was a Jube in normal black tolex. The Jube was introduced in '87 to mark Marshall's 25 anniversary I believe with special cosmetics but they continued to build the amps until 1990 with normal cosmetics. They re-introduced it with the Slash head a couple years later.

I could never really bond with my 2550 and sold it. I still have my 2204.

OK but the original subject was dealing with JMPs and JCMs. But point taken. And I would maintain the 1959RR is a different animal than the 1959s he used. That would be stock 59s. I don't know enough about Rhodes to know if he pushed them with pedals or had them modded to get his tone.

He had Marshall build them for him while in England and that's what he used. Wanted more beef I guess. They grabbed his amp and copied it. Channel I is stock, plugging into CHII gives you the cascaded circuit. Not sure what channel he ended up using. He also used a Dist + and MXR eq mostly.

It looks like a JMP!

Geez... you think they would have kept a record of what they did for him. I just got done listening to Crazy Train. He had to be pushing the amp with something. Way too much gain to just be going straight in.

I can't find it again, but the other day I found a thread (on the Metro forum I think) that detailed the exact mods done to his amp and how it compares to the 1959RR. There's also an article in .pdf form floating around about it. It's essentially the "one wire mod" paired with a few other small changes.

I guess back in the day he liked the Marshall sound but wanted more beef. He went to the factory and a tech took the 59 circuit and modded it to what he wanted. When the did the RI they went to his Mom and got his amp. They opened it up and copied it. CH II has a ton of gain..even CH I has a ton compared to my plexi 59's. It's a cool amp, much darker than a typical 59 amp.

Yeah he used the Dist + and the MXR eq on the studio stuff along with a bunch of double tracking. If you can find a copy of You Said It All, or the Mr Crowley picture disc its easier to hear his basic tone. Seeing him live the tone was awesome! I like the studio stuff too, but it's not much like the basic live tone.

Basically it's CH II being cascaded into CH I with a different presence circuit. You can hear it on my Youtube channel. CH II has alot more gain than a 2203 circuit. Rupe has one too. I've had pretty much all the different Marshalls at one time or another.

On a different note, since you have more experience with Marshalls, does this sound like a typical late 70's Super Lead? https://www.youtube.com/watch?v=U97dcXykcH0

JMP = Jim Marshall Prodcuts

JCM 800 = Jim Marshall's license plate number

There is no 59 - JCM anything.


Steve

Yes there is.. I present to you.. the JCM 800 1959

I had a JCM 800 1959, just got rid of it this year when my Einstein arrived. That amp was the loudest 100W I have ever heard or played its not like a regular 800, it has your typical 4 channel input JMP style. I never bonded with that amp really...
