I recently purchased a Big Muff Pi, but when I hook it up to the amplifier it goes through periods of time when it works perfectly (lights up and turns on), works strangely (fuzz/effect works, no light), lights up but doesn’t work, and doesn’t work at all when turned on (I can still hear my bass when it’s bypassed).
I am using a 9v battery to power the pedal, I don’t own a power cable for it. There isn’t really any rhyme or reason to the times when it works and when it doesn’t – it’s super intermittant. I have already tried changing the battery.
I also looked inside and nothing looks super loose or particularly weakly soldered, but I think from past experience with other electronics that intermittent problems like this are commonly the result of some kind of loose connection or failing component?
Before seeing if I can find a multimeter to borrow and just testing every component on the board, does anyone have experience with this kind of issue? Thank you for your help!
