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 Tone Reaper

Happy Fuzz Friday, everyone! This week I give you the Earthquaker Devices Tone Reaper. This got traced over the Tagboard Effects forum, so thanks to Galapagos for doing the leg work. It's based on the 3-knob Tone Bender, with the darlington pair of germanium transistors simplified into a single high gain silicon transistor. In some respects it's similar to the D*A*M GB-83 Greasebox in that respect. An AC176 is used in the originals but others may work. Socket and experiment as usual. The tone control has also been changed to a BMP tone stack. I redrew the schematic for reference:

  1. Tried some old soviet germanium transistors - sounds good. Interesting fuzz. Are there any recommendations as for transistors hfe?

  2. And one more request - could you make a layout of DB1 here's the link https://guitar-gear.ru/forum/index.php?app=core&module=attach&section=attach&attach_id=7280

    2. Yep, it's got PCB layout. I don't have an opportunity to make a PCB unfortunately

    3. You can easily transfer this pcb layout to perfboard since it has pretty standard spacings
