This is a library of perfboard and single-sided PCB effect layouts for guitar and bass. I'm not an electrical engineer by any stretch of the imagination, just a DIY'er who likes drawing layouts. It is meant for the hobbyist (so commercial use of any of these layout is not allowed without permission) and as a way to give back to the online DIY community.

Greer Amps Ghetto Stomp

Here's another one of Nick Greer's offerings. Like Sean over at Lovepedal, he seems to be getting a lot of mileage out of the Electra circuit. I've laid this out for on-board pots with the board mounted vertically like this:

I saw on the Greer Amps website that a special version of this was made with a BC107 transistor, so use that if you want to replicate the blue version of this pedal.


  1. I have built this one, and everything seems to be okay except the tone control,
    it reduces half of the master volume instead of changing the tone of the effect when it is set at zero.
    what d'you think?

    1. If you watch the video, that's exactly what the "tone" control does. It's not the best design for a tone control. Personally I would probably change it to the SWTC.

    2. ah.. yea I just realize it
      then I've already built it correctly.
      thanks bro

  2. After seeing a demo of this pedal on youtube I considered making this one, for the tone control I put it before the volume using a stupidly wonderful tone control scheme. Works well without reducing the volume. I'm using a BC547 transistor and it's working fine, maybe I'll try using a darlington for higher gain for my next project. Thanks to Effects Layout.
