Ring Modu-Matic
Here’s a PCB and Layout for the Ring Modu-Matic. I have yet to build this yet so use these files at your own risk! The dual gang pot in the lower corner I can’t get rid of, due to my…

Tremolo FX Loop
This is a first draft of an idea that I have been thinking about for a few months. It’s a Tremolo that pans between the input signal and the signal coming through the FX Loop. If no signal is coming…
Tremolo-Matic X
This is Tremolo-Matic X from the Tremolo Issue of Stompboxology by Nicolas Boscorelli. I have redrawn the schematic to make it easier to read. Hopefully this will be helpful to anyone attempting this project. This is Tremolo that pans between…
Ring Modu-Matic
This is the Ring Modu-Matic from Stompboxology. I redrew everything in Eagle PCB. This is an interesting design. It seems to use several different supply voltages. There is a +9v, +4.5v and +5v, +2.5v,
5 Knobs
Here’s an idea I have been wanting to try in a stompbox. Small Bear carries post with long leads that can be used to mount the pot to PCB. I thought these might be good for mounting a board inside…
Your 555 Ticking? Try this…
Here’s an idea to get rid of ticking in your 555 circuits. This image was taken from the Commonsound Triwave.
Revolting Visage
Here’s my take on the Ugly Face/Crash Sync. I took my favorite parts of both and a few suggestions from RunOffGroove and the DIYStompboxes forum. This version uses a different input buffer, which more closely resembles the input of the…
Two Screamer
I had been wanting to build Craig Anderton’s graphic fuzz. But I had never gotten around to it. Though I did find an old 10 band EQ on the street that I thought would make a home for that project. …
MOSFET Boost Layout
Here’s a layout for the MosFET boost. The drawing is pretty sloppy. But this shows the schematic and layout I used for my build. Seemed to work well. Here’s a link to a picture of my build. Here’s a link…
Ugly Face Volume Mod
I like the Tim Escobedo’s Ugly Face I’ve built about 7 now. This is a really fun pedal. Total Sonic Mayhem. Not for Jazz, though I’m hoping someone will take that as a challenge… Something that is not really a…
Screamer
Built Jack Orman’s Son of Screamer last night. Fired up the first time and sounds pretty good. I have not owned a Tube Screamer before. After building this I’m understanding the complaints about the “mid hump” in the sound. The…
9V Sample and Hold
With a great idea from Brian Marshall of Subdecay I managed to get my 9V sample and Hold working. This ties Brian’s Sample and Hold to the Colorsound Wah. This works pretty good. The range of the effect could still…
