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.

Run Off Groove Mockman 2.0

Continuing to knock out the last few ROG designs I haven't laid out. This one's a pretty easy little circuit, emulating the distortion in Rockman amps designed an used by Boston guitarist Tom Scholz. The toggle allows you to go between 80s (classic) and 90s (modern) tones, and it should all fit in a 1590a. Schematic, sound clips and more info on the ROG site.


  1. Check the notes and schematic on ROGs website.

  2. Verified!!

    Very bright distortion (I use a strat), decent sounding, I used a JRC4558, I wonder if it is possible to add a tone control...

  3. Please try ROG Tri vibe, hopefully to fit in a a 1590B enclosure.

  4. I used a 330pf and a 4558D...Sounded pretty good! Cool the Engines!

    1. the 330pf capacitor did you use it as Cx?
