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.

Basic Audio Scarab Deluxe

This is a variation of the Mictester Silicon Tonebender, which is based of the Tone Bender Mk II Professional circuit. John Lyons was kind enough to shed some light on his version over at FSB.

  1. Hello,

    One mistake on the PCB. 4uF7 and 100 ohm to ground is OK but 10k to 100 ohm you must cut.

    Super sound, marvelous fuzz

    1. If you can find a schematic I can. I haven't been able to find one. My guess is that John Lyons is the only one who has one.

  3. First of all, thaks for your work with all the layouts. The error remains in the pcb: junction between 4,7uf(neg)/100 ohm and Q4 (emitter)/ 10k. The layout is fine, i think. Sorry for my bad english!.

  5. Hi, is this from an actual Scarab trace? Or just from one or mictesters posts?

    1. Not quite a trace, but a very educated guess off some info from John Lyons himself.
