  • 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 three stomp switches on top, bypass, boost, tone. I used stomp switches for the boost…

  • 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 looks to be about 6 inches across and the other is about 4 inches. There…

  • 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 build by either bending the IC pins over so the chips are upside down, or…

  • 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 example, uses a very off the wall concept. The input signal is imposed on a…

  • 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. Or, the Really Cheap Compressor with a non-inverting amplifier stage. This hasn’t been tested. It…

  • Tremolo-matic X redux

    After playing around with this for a while I find reducing the gain on the input stage seems to get rid of the harsh noise from a hot input. Not sure if this will work for every circumstance, but it did work for my guitar. To make up for the reduced output I modified the…

  • 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 better than the fist. ‘

  • 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 nightmare to solder. It was actually not too hard. I found careful application of small…

  • 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 while back that had all of the transistors in a row. This made for a…

  • 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. http://www.diystompboxes.com/smfforum/index.php?topic=82764.0

  • 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 LFO seems to produce more of a square wave.
