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.

AMZ Dr. Quack
The Dr. Quack is Jack Orman's improvement on the EHX Dr. Q envelope filter. Basically, there's an added input buffer to increase the input impedance (which is kinda low in the Dr. Q) and offers better range control. Check out Jack's blog post on the circuit for more information and a few mods.
