Hi. I have a 79 JMP MKII Superbass that I would like to get a much more aggresive sound out of. It currently has a Master volume mod and a Jumped input mod. I don't care for the jumped input tone as it seems buzzy. I don't think it needs an added pre amp tube but who knows. Are these amps solid state rectified? Would a valve rectifier add more overall balls? I was also thinking of a half power mod as the amp is LOUD and I can't open it up at the gigs we play. Any suggestions would be awesome.
