  • Boss PS-2 schematic

    Anybody have a schematic for a Boss PS-2? I have a really bad volume drop for the delays, while the pitch shifting section is fine.

      Were you able to find the reason for the volume drop with your PS-2?

      I have a similar issue with mine. With balance at noon the first repeat is the same volume as the dry signal, but I only get five or six audible repeats even with feedback at max. Output from pitch shifting modes seems fine

      I should also add that I'm almost certain that the feedback has reduced since I bought the pedal. I was underwhelmed when I first got it but now I reckon that it was failing when I bought it and has got progressively worse. Was yours ok in the past?

        Unfortunately no. Every so often I go at it again trying to find the issue but I'm not sure what it could be. I really thought it would be the electrolytic capacitors as some of them tested poorly, but swapping didn't change the problem.
