  • Kustom iii Lead SC No reverb

    Checked tank and leads going back to board, all have continuity. Unable to track down a schematic.

      Wondering if anyone has any ideas about reverb on the board?

          So all leads from board to ground have continuity. Here's photo of board. Wondering what component is associated with reverb besides the pot?

            Numerous components.

            Look on the board solder side, what number board is it? PC5083 or something similar.

              Did you measure DC resistance of the tank input and output?

              Basic reverb tests usually are to disconnect leads from the tank. Touch tips of leads with your finger, listen for some buzzing to come through the amp. This should only happen with one lead (the reverb return). If that works your return circuit is working (you can turn reverb up/down and make sure that is OK too at this point). If that works you can hook the tank up and bang on it a bit with the amp on, you should hear some crashing sound through the speaker. If that happens the tank is probably good. If both of these tests check and the DC resistances are right then it has to be in the reverb send circuit.
