Hello all, greetings form Portugal. My preamp jmp1 when in OD 1 or 2 has sound, but its not the usual volume. I have to crank the volume all way up to get a room level volume. In clean mode, all cranked up. I only get a very very weak noise when strumming the guitar. Sometimes when in OD mode there are some slight volume variations. Tried 2 power amps. Same problem It is the second time it happens. The firs time after some minutes and rechecking cables it was ok again. But now again, it is definitely no cable. any thoughts? Cheers!!
