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.

Valve Wizard Equinox II
Here's a reverb circuit that doesn't require a Belton brick–the Equinox II by Valve Wizard. It uses 2, PT2399 delay chips with a pretty standard input/output buffer built around a TL072. The original uses a J112 for switching the tails function, but I've simplified that with a just DPDT footswitch. Use one side of the DPDT for turning the reverb on/off, and the other side for LED indication. If you don't want/need tails with your reverb, just jumper the 2 switch pads. It's gonna be a snug fit in a 1590B, but it will fit.
