How do I fix a zoom G1 guitar pedal?
my brother was standing on my amp to hang something and it fell. he said everything was fine, but then I tried to use my pedal and the knob to the left (the one that changes between what part of the effect you edit) wasn't working right. it doesn't do anything when you turn it, and only works when you push down on it. I have a jam session tomorrow, so I need to know ASAP.
