I recently dug up my old Digitech RP6 and was trying to get the wah pedal working. Despite following the manual to make sure I hadn't missed anything, only the top end of the wah works (the "ah"). When pushing the pedal back to the lower end there's nothing there and volume just goes down (to 0 when fully pushed down).

It's an interesting way for it to break (if it had to), making me wonder is there a microchip for the "W" and another one for the "ah"? like my "W" chip is broken?

Wish I hadn't sold my Dunlop Cry Baby. Anyone know what kind of wah is Piotr using from halfway here? I can't decipher form the gear list given.
