Hello. I am curious if any of you have a schematic (s?) for the ORIGINAL, I think USA made Whammy Pedal. Thanks.
Are you trying to clone it or repair one? You won't be able to make a clone using just the schematic, you'd need the code as well.
Or are you trying to add the "auto-ranging volume" circuit to a WH-4?
I have an original USA WH-1 that is a bit on the fritz, I would like to get it repaired.
email digitech, they will supply you with the .pdf . at least, they did for me like 6 years ago.
