Axe-o-Matic

Here’s a new drawing from the Stompbox Cookbook. This is a passive mid control. Could be a good alternative to the standard Guitar treble roll off type tone control. The pot should be a dual gang linear.

Bee Baa

This is a Roland Bee Baa Fuzz. It’s sort of a booster followed by a two transistor silicon fuzz. The sounds is pretty heavy and doom like. Interpret that how you will. The original came in a larger case with…

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…

Distort-o-Matic VI

I’ve been fascinated by the Stompboxology and Stompbox Cookbook projects for a long time. I’ve only built a few and many of the ideas are hit and miss. The concepts presented are compelling none the less. The Distort-o-matic VI for…

Compressor thing

Here’s a my take on the LED  compressor thing. Really this is just a “mash up” of mictester’s “Really Cheap Compressor and the John Hollis Flatline compressor. You could look at this as the Flatline with a simplified LED driver.…

Ugly Face

Here’s a picture of an Ugly Face I made recently. For the graphics on this I used PnP. Not sure how this is going to work out. This is second effect I did with this method. This one came out…

Shocktave first impression

This worked right after I found a small solder bridge grounding the input cap. The PCB layout I posted has some very small traces that are very close to the ground plane. I thought this was going to be a…

Shocktave PCB

I have been thinking about making Joe Davidson’s Shocktave for many years now. I have yet to build it, the PCB in this post is unverified so far. I’m finally getting around to it. I had built a BSIAB II…

Clipping diodes

This is the classic route to distortion. It seems to be included in many designs. Clipping diodes to ground have many different configurations and choices of diodes. Here’s a great thread talking about clipping diodes to ground.

Casualty 4 Phaser MKII

Just tested this one again. My mistake the shape pot is working. It seems to me that the Width pot seems to square off the LFO wave form as it is turned up. With Width all the way up the…
