Hi Napynap, thanks for your reply. Yes the master volume did work before. Now all i get is static , and a fluctuating volume, and not the normal fluctuating issues everyone else has. It does do it on all patches, as well, I have tried without the volume pedal, and the amp is either putting out static, or if I play with the master volume It will stop for a bit and I get very bad fluctuation in volume from full blast to nothing at all, and it doesn't matter where the knob is pointed to, even when I have the volume knob turned all the way down. It seems to me to be that the pot had gone bad. I have heard that it may just need cleaning too.
I have experience in electronic and soldering, but its been a long time, and i don't have the proper tools anymore. So changing out the pot wouldn't be too challenging for me.
