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.

Greer Amps Sucker Punch

The Sucker Punch uses the popular combination of a JFET and 386 op amp, much like the Lovepedal Black Magic/Purple Plexi, or DAM Sonic Titan. Nick Greer put his own spin on this and it sounds pretty good. The 100k trim pot is to bias the drain of the J201. Set to 4.5v and then adjust to taste.


  1. Verified. Can't believe cool sound from pretty small schematic. Very bright tone with powerful distortion. Thanks a lot for sharing this schematic.

  2. What kind of capacitors (model type and all value)you use for this pedal? Thanks
