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.

Devi Ever Electric Brown

Here's a unique little circuit from Devi. Plenty of gain on tap to go from just a boost, to an overdrive, to fuzzy the more your turn up the volume control. The Pregain control acts more like a tone control, panning between 2 capacitors. The first transistor stage is kind of like an Electra Distortion, and then I don't quite understand the 2nd transistor, but it works and it sounds good.

  1. i suppose emitter of upper transistor should be connected to ground... am i right?

    1. I would have thought that too, but from what I can tell, it's not.

  2. This producing tone-sound richer than Purple Plexi 800.
    And your PCB layout was perfectly good!
    This beauty grounding reduce noise very much!

    Thank's Bro
