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.

BearFoot FX Baby Pink Booster

Here's a cool little booster from Bjorn. Fairly typical JFET boost but the way the originals are wired, when the effect is bypassed, it's buffer. This layout reflects that original wiring, so wire the In pad to the input jack, Out pad to the output jack, and use a DPDT footswitch. If want to wire it for true bypass, jumper the 2 switch pads at the top of the board and omit the 150k resistor going from lug 1 of the Boost pot to ground. Or you can wire up a SPST switch to go between buffer and boost. Lots of options with this little circuit. Works well off 18v too.


  1. Thanks for this layout
    Can i ask a request?
    Please make throttle box distortion layout

  2. Hi! A spst switch would be fine for this layout?

  3. Excuse me, how to connect 3PDT switch?

    1. Check the general layout notes tab at the top of the page

    2. Can i make to be one with another pedal effect in one box?

  4. Verified.
    Used 15k's in place of the 14.7k's.
    The circuit is a clean, transparent boost as advertised.
