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.

Dirt Master

 Here's a little something I whipped up the other night on a whim. Actually built it on the fly before I even drew up a layout. I was trying to build something with some old mojo caps I found on my bench, and it initially started as a treble booster, but I ended up wanting more gain. Initially it was based on the EQD Arrows, but added an extra cap off the emitter (ala the Rangemaster) for more gain and snarl. I used a germanium transistor with an hFE of around 230. Worked well with a silicon transistor as well. Room for experimenting with the input and output caps. Should fit easily in a 1590B.
