PICs are actaully pretty feeble things processing wise.
And I thougth they were the answer to all processing problems, is the clock speed to slow?

Do you know the spec of the inductors in the Wah Wah? In therory, I could probably wind such an inductor...but why? (are they hard to get or something unique about them?)
No not hard to get but at £20 from the gud ol US its a bit pricey. 520mh is the magic value apparently. Read an article on old vintage Wah's and it seems that the sound is due to the magnetic build up of the pot core and suggested that an additional second winding could provide this varible magnatism (if that sounds correct) to recreate the sound?

I know lots about guitars but electronics to that level is beond me...:heehee:
