ok, so i just recently sorted out my busted compression sustainer (store gave me a new one) and now i find out my slash wahs broke it powers up fine and the distortion kinda works (not as harsh as it used to be) but no sweep. Im pissed about this one cuz i bought it used about a year ago so i cant just take it to the shop and have them give me a new one. Anyone know what might be wrong with it?
