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.

Black Arts Toneworks Fnord

Got a little Eagle excursion for Fuzz Friday. Here's the Fnord from Black Arts Toneworks. It's pretty much the same as the Escobedo Digital Octaver Fuzz with an added diode lift switch (though that's jumpered in the originals). It's a pretty gnarly fuzz with a wide range of tones. For you perfboard builders you should be able to translate this onto perf pretty easily.

Here's the schematic for reference:


  1. Great! Thanks, as always.
    Which program do you use to make the schemes?

  2. Would u mind to share the eagle files? 🙏

    1. I don't share design files, but if you want to order a board from OshPark you can do so here:

  3. Verified!
    Nice gated/velcro fuzz

  4. Verified!!! Just a few notes:
    -the cd4070 IC is very sensitive, so be careful and don't touch the pins with the hand, if you touch it, sometimes the response is very different and the notes will be excesive gated.
    -Put a trimpot instead the 100K(R7) and try different values for C5,this will help to achieve a better octave effect.
    -1N4148 for clipping diodes works perfect, 3mm red leds works nice too.
