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.

Frantone Lo-Tone Classic Fuzz

Here's an interesting one from Frantone for Fuzz Friday. Think the first half of a Big Muff into an LM386. Schematic over on FSB here.

    1. If you're after poly mylar caps, check out Tayda Electronics. For higher quality parts I suggest Arrow or Mouser.

  3. Can we use mpas13 instead of mpsa18?

    1. The MPSA13 is too high hFE being a darlington transistor. 2N5088, 2N5089, BC549C or even a higher gain 2N3904 would be better substitutions.

  4. Hi there could you recommend an equivalent diode for the 1N34A (if such a thing exists)? I'm itching to build this and that is the only component that I can't get my hands on.

    1. Those are being used as clipping diodes, so almost anything will work. You can try other germaniums (Russian D9 diodes are what I use for germanium diodes these days), or others like 1N4148, red LEDs... they will alter the tone a bit, but it will still work. Use sockets and try out different diodes and see what sounds best to you.

  5. I built this on perfboard and everything works like it should. Sounds good, too. Thanks for this and all the other great layouts.
