just tried out the Russian Pi Big Muff again. when i first plugged in i didn’t get any sound when turned but i turned the sustain knob and a crackle came and i had signal, played on for an hour or so, then came back a few hours later and whenever it was in the loop there was a terrible hum. This brought back memories of what its problem was a year or two back, it would eat up a battery in a day or less.
i opened it up and saw that, where the red and white wires coming from the 12volt battery attachment solder to the board, it looks pretty black and crispy.

i did have to replace the power supply for the holy grail because the old one had broken. i just dug it out and now it wont come on at all and wont let a signal through what so ever.

they both seem pretty doomed at this point

okay, i think i’m going to try and resolder those joints. if that doesn’t work i guess ill try putting in new capacitors. not sure what kind i’d need exactly or how hard they could be to gt ahold of.

thanks
