Fulltone Ultimate Octave

Happy Fuzz Friday everyone! Had a request for this one. It's basically a Foxx Tone Machine with some value changes and a couple additions, namely a switch to shift the range of the tone control and the octave switch is a footswitch. Here's the schematic for reference.

  1. would 1n60 diodes fit this project? I have plenty available here

  2. Thanks for the layout, will need to build and verify.
    One question: will SPDT footswitch be enough for Octave? From what I understand, there is nothing by bypass or select here, and this switch only utilizes one contact group to conntect or disconnect Oct1 and Oct2 pads, right?
    Thanks in advance!

    1. A SPDT footswitch will be fine, but use a DPDT if you want to include an on/off LED. Use one side for the octave and the other for the LED.

  6. After some digging, I tracked down a higher quality schematic image.

    I'll start the build once time permits me in a few days; For now though, can anyone confirm this build? Hopefully the schem will help the cause.

    1. What transistor u use ?
      Cause 2N series and BC series is different pinout, just rotation 180 degree, base is same position but Emitor and collector is baxkward position.. it may can help u
