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.

Barber Dirty Bomb

Gotten several requests for this one. Your wishes have finally be granted! Originals have the Sub Bass control as an internal pot, but it was pretty easy to include it externally, so you have options. It's designed specifically for a 125B with board mounted pots, but would fit in a small box with the pots off-board. Schematic, etc. on FSB.


  1. Pls. mark it as verified. I will try to mode the clipping by trying some other diodes or an LED.

  2. It sounds great, but the sub bass control does not make any change in the sound, the difference is very little.
