    Does anyone know how I could build a 1 button footswitch to control the Tremolo Only? I have a single button switch but it knocks out the reverb and the Tremolo has a clicking sound with each pulse when I use it. I usually play with a touch of reverb so not interested in having that foot switchable, and I use a pedal train nano and don't have the space for a full sized footswitch. Suggestion would be great - thx.

    It depends - is this a vintage 2 RCA jack model or a more modern 1 1/4" model?

    Cool - so here is the schematic for the reissue footswitch

    So you want to make a switch that connects tip to ground using a stereo plug.

    Your foot switch will need a TRS (tip/ring/shield) 1/4" jack.

    If I'm reading the schematic right then closed switch for vibrato = on and closed switch for reverb = off.

    If that's right then don't connect the jack's ring terminal (reverb) to anything for always on reverb. Tip and Shield connect to the vibrato foot switch's two terminals.
