Ground Zero 1977 Marshall JMP Super Lead 2203 conversion and non-Jose mods

This Super Lead was converted to 2203 spec and then modded for more gain and better dynamics. There is a 3 way gain structure switch in upper right input hole and a SAT switch in lower right.

Amazing clarity on those notes but still has a lot of vibe

It ain’t no Jose…but still pretty cool!

I have a 77 JMP 2204. It has Mustard caps. They stopped using them somewhere around that time.

[@groundzeroampworks780]

Yes, you’ll see both Mustards and the green chicklet caps in 77’s.

[@groundzeroampworks780]

@@truescotsman4103 this one didn’t have Mustards. I replaced all the caps anyway though.
