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.

Maestro Bass Brassmaster

The Brassmaster was originally designed for bass and also picked up by guitarists. The circuit is very unique and originals are hard to come by. I was able to lay it out to fit in a 125B with board mounted pots.

  2. Probably a silly question cause I’m new to building but why so many switching connections for the brass? On the OG pedal i thought there were only two options for brass? Does it just mean the toggle switch for the brass is a 3PDT style switch and the harmonic is a SPDT?

  4. Just built this and can't get it to work. Not done debugging yet though :)
    Just wanna ask what schematic you used for it because I am quite confused by what I see on schematics and other layouts. Also, I suppose the switch numbering is the standard
    1 4 7
    2 5 8
    3 6 9
    right?
