I have an old Morley Wah/Fuzz that I'm trying to get in working order. It makes an audible feedback that changes when you move the pedal, so I'm assuming it has something to do with the jack. Does anyone know the name of a good, affordable repairman, preferably in the New York area? Also, are there any resources that could help me attempt the repair myself? (Note: I have no experience working with electronics.)
