  • Bypass issue with Vox Treble Booster clone v806



    Hello there,

    Im building a little Vox treble Booster clone.

    The pedal is working fine when activated BUT the Bypass signal is non existent - no sound at all, not even when I remove battery.

    I have checked the dpdt footswitch wiring and even changed the footswitch all together. When I remove the ground wire from one of the lugs of the footswitch (as per your standard pedal wiring diagrams), I get a bypass sound that is reminiscent of "Tone Suck" aka complete loss of high end. Pedal always works when activated though, its just a problem with the bypass signal.

    I'm using a strip vero board, and have checked and re-checked my ground,9v, and signal rails. Both jacks are grounded to GND rail on board. Could it be that my GND Rail is right beside my Signal Out rail on the board and maybe causing cross-talk? Im thinking about anything here.




    Does anyone know what this can be? Its really doing my head in, any help would be great, thanks!

        In the photo you have conductors going to all contacts of the switch, but in the diagram only to five.
        Possible when switching on the bypass, the signal signal is connected to + batteries

          i just went by the standard dpdt true bypass wiring diagram, i didnt even pay attention to the diagram switch layout until you mentioned it

            Also, on the schematic, there are no jack grounds connected to the switch (black wire).

              Sorry but you didn´t.

              Please post the one you think you built so we all compare it to the picture.

              Don´t understand what you did, board in-out points are not identified, we don´t know what´s happening on the invisible side.

              I don´t even know which is the input jack and which the output one, go figure.

              Also you permanently soldered the battery to the board, it is not switched either by a jack leg (like most pedals do) or by the footswitch (like on the schematic) so it will run down in a short time.

              Sincerely trying to help, but quite confused at the moment, please post what´s asked.

              On any case, I suggest you remove present wiring, wire a regular true bypass switch without installing the board yet, you should be left with two flying wires: TO effect and FROM effect.

              FSW must work as expected:

              * position 1: true bypass, NOTHING connected to PCB, sound passes through.

              * position 2: no sound since the path is broken (no PCB)

              To test it, join both free wire ends, you must restore sound.

              No effect, of course, but this proves wiring is right.

              THEN you insert whatever effect you want, including VOX Treble Booster.
