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.

CMAT Mods Signa

Got a request for this one. It's a barely modified Tube Screamer with a clipping switch to go between silicon and red LEDs. The switch is a SPDT on/off/on by the way. Gearmandude really seems to like it.

  2. Can you find a schematic and make a Kent 6400 distorter?
    It's got 4 resistors and 5, 15 & 25uf caps, even though it may seem similar to a Schaller fuzz it's different and am keen to hear it. Uses ac 151r transistors.
