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.

Marshall Blues Breaker Mk.I

The Blues Breaker was designed to emulate the vintage 2x12 Marshall combo, and was introduced by Marshall in 1991. Great at pushing a clean amp into breakup and sounds great with single coils. There has since been a Bluesbreaker II, which many claim to be inferior to the original. This layout is for the original model with onboard pots and will fit in a 1590B.

Note that the PCB layout is half a row (0.05 in/1.27mm) taller than the perf layout.


  1. Hi, This layout is verified:


  3. Why dont you publish the schematics as well ?

    1. If I don't draw the schematic myself I don't post it. Often times I'll link to it, especially if it's from a source with extra information on the circuit like or a FSB/DIYSB thread. Typically though, the schematics are easily found online. A little Google searching never hurt anyone. ;)
