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.

Univox SuperFuzz (modded)

Here the Univox SuperFuzz with the mods done by FSB member derringer. It replaces the stock tone switch with a pot, as well as a few other useful mods. Socket the 2 ceramic caps going from the base to collector on Q1 and Q6 and try some different values (I'm guessing in the 100pf to 500pf range). This one's a little on the wide side, so you'd be hard pressed to fit it in a 1590B, but it should fit quite nicely in a 1590BB.


  1. I've built several different Super Fuzz layouts. The Derringer version sounds best to me. I'm going to give this one a go. Building that thing on vero is no fun!

  2. It's verified :)
    This layout is really great. Thanks so much for doing it!

    The bass players out there should definitely build this one.

    1. That was quick! Thanks for verifying!

    2. You're welcome. I have some time off so I'm feverishly building all the stuff I've had on my workbench for the past few months. It's really rewarding to finish projects and make my work space cleaner in the process!

      btw, I sourced some NOS Matsushita 2SC828s for this and WHOA. I'm glad I went ahead and used all my finest parts on this layout 'cuz it sounds great. Thanks again and again.

    3. Here are some photos of the build I did using the PCB layout:
