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.

Ashbory Bass Preamp

The Ashbory bass was first introduced in 1986 and is/was a half scale (18") fretless travel bass with a piezo pickup and built in preamp. That preamp is essentially a Baxendall tone stack feeding into the volume control, into an op amp based gain stage. I stumbled across the schematic and thought it would be a good addition to the library. Should fit nicely in a 1590B, or you could wire it into a bass.

    1. It means that the volume is very low.
