  • Silicon Tonebender

    I built this Silicon Tonebender posted by mictester over on Freestompboxes. I used this layout. Everything worked the first try and it sounds good. I used BC109CN for transistors. These sounded good and have that metal can with a little tab mojo. I used a ceramic .1µf cap for the input cap and skipped the…

  • Paul Falstad’s Circuit Sim

    If you are into making things with electronics you probably need to test them out from time to time. Paul Falstad has a really great on line circuit simulation app. It’s a Java applet. Try it out here:  http://falstad.com/circuit/ Here’s a picture of a Fuzz Face I mocked up. Notice the scope at the bottom.…

  • 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…
