    What pots are in the JMP Mk2?

    We've got a 50 watt jmp mk2 1987 model, I believe it's a 76 (H serial code) and all the pots are pretty bad. We've metered them and they've got a bunch of dead spots. I can't seem to find anywhere that says what the values are to replace them, Thanks..

    Sold: Vintage Mid-1970s Marshall 4x12 Slant Cab, Celestion Black Back Speakers, Jk23

    I'm selling my mid 1970s Marshall 4x12 cab. I used this with a '76 JMP 1987 50W head for a while, but have sold the head and am no longer in need of a half stack.
