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.

Earthquaker Devices Tentacle

Had several requests for the Tentacle, but it's just more or less a Dan Armstrong Green Ringer clone. But I had the idea of making a Green Ringer layout with the bypass footswitch board-mounted so we'll just call this layout the Tentacle. Should fit easily in a 1590A. If you'd rather a fabricated PCB to build on, check out the Darkmantle on the store.

    1. Anything medium to high gain hFE should be fine. 2N5088, MPSA18, BC549C etc

  6. Thank you for the layout! I used it to create a double octave up with selectable Si/Ge clipping diodes in both circuits. Sounds beautiful. In this demo I played an acoustic Martin into a 65 Princeton Reverb: https://youtu.be/1euyGmRCjUA

  7. Hi, noob question, but there's a 47n capacitor in this schematic that is not in the layout. Is it better to omit it and just go ahead with the layout template?? http://guitar-fx-layouts.42897.x6.nabble.com/file/n34610/EQD_Tentacle_schem.png

    Thanks!
