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.

Got a request for this one. It's based on the old Maestro MFZ-1 and was put together by Brett over on the DIYStompbox forum. Apparently it has a very similar sound to some earlier Black Keys tones. Original thread can be found here, and a sound clip can be heard here.


  1. Good job buddy! What about Dumbloid ? Pedal the sound of elegant and interesting in its own way, even in contrast to the Zendrive. Good luck and thank you for all that you do !!!

    1. Sure:

  3. Verified! A bit noisy when I turn up the sweat, but I think that has a lot to do with my test rig. I'm surprised how distorted yet clear this pedal is. I tried and few different ICs and I think the 72 is clearest one to my ears. Thanks for sharing!

  4. Very fun, good Black Keys tones, between vintage distortion and fuzz ;)
