Vintage 1974 Marshall in for some major mods. All tube effects loop with footswitch relay bypass, footswitchable mute, footswitchable dual masters. Added gain stage and fully cascaded for a savage hi-gain tone. Think Friedman HBE.
This bad boy took awhile but was it ever worth it!! Even installed dual bias pots with el34/6l6 switch. Dont worry haters, this amp had holes drilled in it for an added tube and a series effects loop allready.This is a great players amp. I would never do this to a minty JMP. Video coming soon.
