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.

Burns Buzzaround

Here's an interesting take on the Tone Bender Mk III. Original units were positive ground, so the perf side of the layout reflects that, while the PCB side is set up for daisy-chainable negative ground.


  1. Sorry, but where are in and out? In to 2M and out Timbre-2?

  2. Yes, its works, I used soviet transistors MP-series. Sounds great, but pots works very strange...

  3. Any chance on finding out where the in and out go? I etched this without realizing they weren't there haha 😀

    1. Hahaha! My bad. Input is that unlabeled pad right in the middle on the left. Output is from Timbre 2
