Hello,
I have a MXR Guitar Pedal here that turns on, passes audio but does not add the effect. It has a high pitched squeal that varies tone depending on delay speed.
Its a analog delay pedal using four BBD (BL3208A), one compander (SA571D), one clock (cd4047), one TL082 and one 33178.
This pedal is prone to some issues (ESD), but i replaced the common faulty transistors and the problem remained. In fact, the original ones were still good (tested on component tester).
Anyone familiar with this pedal to give me some light?
Thanks, have a good day
Leandro
