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.

BBE AM64 American Metal

Here's the BBE AM64. While "Metal" is in its name, it seems more suited for heavier rock sounds. 70s metal at best. Nonetheless, it's a very good sounding distortion box. The circuit is essentially a Guv'nor with soft clipping instead of hard, along with a DS-1 tone stack.


  1. can you do a mad professor snow white auto wah and a zvex machine? i have a problem building that in a vero.. =(

  2. can you do more BBE pedals?

    1. As far as I know, it has not been verified yet. (see the tag that says 'Unverified'?)

  4. Easy build, with great 70's era hard rock leads and chords, made a couple of changes to the pcb to enable board mounted pots (just a preference of mine) but kept all component values the same as the drawings. Well done, thanks!!

  5. Halo, you have layout BBE 427 DISTORTION

  6. Hello, first of all I want to thank you for your work, I assembled this pedal the other day, everything works, I used a 5532 op-amp, it works better than 072 for me. In the future, I want to try different diodes, I wonder how it will affect the sound. Thanks again, all the best!
