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.

FuzzHugger FX Doom Bloom

Fuzz Friday! Do you want a fuzz with a bunch of knobs, versatile tones, and works on guitar and bass? Good. Here's the Doom Bloom from FuzzHugger. Think of it as an Electra distortion pushing a Bazz Fuss with a handful on pots thrown in for a bunch of tweak-ability. It'll be a tight squeeze in a 1590B, but it should fit.


  1. Looks like there is a missing connection here. Collector of Q2 should connect to the junction between lug 2 of High, which should go to lug 2 and 1 of Body. Lug 3 of Body should only go to the 1uf cap.

    1. Thanks for catching that. I must have messed it up when I reorganized Q2. It's fixed now.

  2. i think that it's still not quite right. the collector of Q2 should connect to lug 2 of the high pot and lugs 1 & 2 of the body pot. yours shows it connected to the 1uf. i used your first layout (with errors) and then corrected it like this:

    i built it up and tested it and it works like the original pedal.

  3. Hi!

    I had to make certain changes to your layout (similar to ones suggested by John) to make it work.

    As usual, top jacks for the win:

    My regards.

  4. FWIW, here's a couple of pics of my build:
