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.

Castledine Electronics The Wizard

Here's another take on the cascaded JFET overdrive design. This has a similar goal to the Catalinbread Sabbra Cadabra in trying to sound like Tony Iommi with a treble booster feeding a tube emulator. The Wizard is...

A new distortion pedal, inspired by Tony Iommi's guitar sound on the early Black Sabbath albums. It is well known that he used a modified Rangemaster to drive his amps, so the same principle was used for The Wizard. The first gain stage is essentially a Rangemaster, using a germanium transistor, but tweaked for a full range boost. That drives a distortion circuit which has been designed to give something of the tone and feel of a Laney Supergroup amp. Obviously, there is no substitute for a full stack at volume, but The Wizard has a similar distortion character and responds well to picking dynamics. 

I've laid this out specifically for a 125B enclosure with top mounted jacks.
