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.

EQD Black Ash

Hope everyone's having a safe and healthy Fuzz Friday. Found out the Black Ash had been traced and figured I'd draw up a layout. I figured it was a pretty straight Tone Bender Mk II clone, and it is with a simple tone control tacked on just before the volume pot. Was slightly surprised that it uses all silicon transistors. The resistors in the originals are old school carbon comps for the mojo. Here's the schematic for reference. You can probably get away with 4.7k and 47k resistors instead of the 4.6k and 46k resistors listed. Also alternatives to the 2N3903 would be 2N2222a, 2N2369, etc. Shoot for 100-150 hFE.

JSA Ampldrive

Like many, I find myself working from home for the foreseeable future due to the COVID-19 pandemic. Most of my time so far has been trying to accomplish my day job in sweatpants and help my wife do hers (aka, kid wrangling), and I haven't had much time to build anything. But yesterday I did carve some time out to create today's layout. Shout out and thanks to Simon from JSA Effect Pedals for sharing some of his creations with me. Check him out on Instagram for build notes on this particular circuit. It's a pretty simple drive and should go together pretty quickly if you have all the parts on hand. And if you don't, he's got some notes on alternatives. Enjoy and stay well folks. Thinking of you all.
