Webcor amp
I traded a Fuzz Factory Clone for what looks like an old PA that’s been modified to work as a guitar amp. The Webcor has two speaker connected with what looks like a giant oil and paper capacitor. One speaker…
Stompbox Cookbook PCB layouts are BACKWARDS!
I just started building up a project and I realized the PCB layout I printed from the Stompbox Cookbook is backwards! Beware if you plan to build a project from any of these layouts. I think I can save my…
FSH-1 PCB
This will be the fourth time I try to build one of these. I made a PCB for the original using the layout from GGG. I never finished this. Then I built and finished a second using the layout from…

Some PCBs
Here’s the current projects. Two Echo Base and two Casualty 4 Phaser shifters.

What am I missing?
Assume there’s your favorite booster at the input, what is D2 doing? This is the most common clipping arrangement that I have seen. It seems that D2 does nothing. If the boost at the input is running off 9V then…
