Distort-o-Matic XI demo
This is an audio demo of the Distort-o-matic XI from Stompboxology. Check out my build page for a schematic and images of the finished project.

The Sultan Fuzz
This is my entry in the End of Days Fuzz Challenge 2022. Based on the Fuzz Face with an added two band tone control similar to the tone controls on Orange and Ampeg amplifiers. I wrote about this circuit in this post: The Sultan. I was pretty happy with the sounds on the breadboard so…

Super-Fuzz V2
I updated the Super-Fuzz Board to fix a problem with the last version. The prototyping service at PCBWay.com is very inexpensive, which facilitates my workflow. The schematic I used for this project came from Freestompboxes.org. It’s based on the original with a couple mods. The Tone switch has been turned into a pot to provide a range…

Ugly Face black with dots
I did another Ugly Face. This time on a black gloss enclosure with milled dot pattern. Milling this design took over an hour. These enclosures are not flat on top! Some of the dots on the upper right did not get milled. I had to pull those out of the original SVG image, make a…

Stone Bender #2
This pedal sounds so good I had to make another! Check out my first build and the build page. I manufactured these boards at PCBWay.com. This board is posted at the PCBWay Shared service. You can order and build it for I milled a gray powder-coated enclosure. It looked better than I was expecting. It’s got a…

Univox Super Fuzz
Super Fuzz is a circuit that has many variations. It’s one of the popular building blocks that has been used for decades. It’s built around a full wave rectifier that produces an octave fuzz sound. similar circuits that use the full wave rectifier: Super Fuzz Kay Fuzztone Univox Super Fuzz Honey Psychedelic Machine Third Man…

The Baron
This is my second entry in the End of Days Fuzz Challenge! The idea was to build a circuit similar to the Proco Rat replacing the LM308 with the LM386. The LM308 is a single op-amp the LM386 is an audio amplifier. The chips are similar but also very different. LM386 The LM386 is similar…

End of Days Fuzz Challenge
End of Days Fuzz Challenge is a challenge to make develop new Fuzz circuits. Here’s a description from the web site: It is an open invitation for pedal builders/ companies of all levels. If you – or anyone you know – wants to join in, go for it! All you need to do is read…

Bork Bork
Just built up a Bork Bork from Breakfast Audio. This is a clone of the Ibanez Wau Wau Fuzz. As far as I my “in depth” research can tell the Wau Wau Fuzz was originally a Fuzz and Wah in wah type enclosure. It had both a Fuzz and a Wah effect in the same…

Kay Fuzz Tone
Here is a kay Fuzztone clone. This is an octave-type fuzz that uses a full-wave rectifier. It is similar to the Super Fuzz and all its variants. The Kay Fuzz Tone uses fewer transistors than the Super Fuzz so you could think of it as a stripped-down and simpler version. The kay Fuzz Tone came…

Distort-o-Matic XI Stompboxology
Here’s another project from Nicholas Boscorelli’s Stomboxology newsletter: Going Discreet. Described by the author as: All-transistor distortion box with aggressive tone controls. Nicholas Boscorelli When I look at this I see a diode clipper similar to the Electra, DOD 250, MXR Distortion+, Proco Rat, and others, combined with a Super Fuzz octave Fuzz type octave…

Bobtavia analysis
This is a quick look at how the Bobtavia works. The Bobtavia is uses the LM386 to amplify the input signal. In the default setup the LM386 has a gain of 20. The output of the LM386 runs through a 220µ C4 cap into a small audio transformer. The input appears at one output of…
