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.

DeadAstronaut Space Patrol Fuzz

For Fuzz Friday here's DeadAstronaut's take on the good ol' Big Muff. It features a toggle switch (Fat/Thin) that changes the output capacitor from the first stage, and a rotary switch (mode) that changes the sound type. In the designer's own words:

It's basically a classic big muff with fat/thin switching, plus 3 other modes for synthy, buzzy, octavey, duck and swell type switching diodes and collector resistors. Rather  like a bias control on a fuzz face...but for both collectors.

Here's the schematic for reference.


  1. Nice!! Thx for the great layouts man!!
    Can you pretty please, do the Abductor/Abductor II delay layout?!?! That'd ne awesome!

  2. Hi, Just to let you know I have built this and can say it is verified.

  3. Share the scheme. I can not find anywhere.

  4. The link to the schematic is fallen. Can you upload it again? Thx.

    1. It's not in my dropbox. I linked to what DeadAstronaut had posted over on DIYSB, but it looks like he's moved it. Sorry!
