Let's find a way to get an M^4 to Cliff
I’ve contemplated asking Cliff if he would be interested in taking mine for a bit to model, I think it would be a testament to mikes amps, and finally getting the recognition that he without question deserves. And, it’s just flat out insane sounding. Mine was called the “head from hell” mod, 1978 JMP 2203, in a purple headshell. It’s got an extra gain pot, and both are pull knobs that add more gain,eq, and overall aggression. It also has 2 extra preamp tubes, and I believe the entire tonestack was reworked. It’s wild for sure. Mike says he remembers doing mine in about 95 or 96, as he only did about 10-15 of these. He said that mod is without question the most insane mod he did on those amps, and by far the most aggressive. It is my prized piece, for me anyways!
But if Cliff @FractalAudio is interested, I might try and make it work, especially if there is a big push for it.
