Thanks fdor your reply Govmnt_Lacky
I opened it up and removed the pcb from the metal chassis. At first i thought the problem was the gain pot, since it made big noise when touched, so i decided to remove the small pcb with the gain pot (btw, two of the lugs are soldered together and there's a trace cut in the pcb, as well as another trace cut in the main pcb...i'll attach some pics later)
After doing so, i plugged the guitar and the signal is completely overload, sounds like straight fuzz (which is kinda cool in a way!). Just plain fuzz on both the dry and wet outputs, and the input completely overload....BUT, not crackling like before. So, after doing this, may the problem be just the gain pot?? Or could the problem be caused by any, or some of the opamps??
Mine is a Whammy Pedal II Rev C. The Eprom version is 1.10....I think it's one of the first runs of Whammy II
I'll attach some pics later
