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…

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…
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…
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,…
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…
Bobtavia by Bob Starr
Bobtavia is an old-school DIY octave fuzz. It’s a lot like the Roger Meyer Octavia but uses an LM386 instead of transistors. The Bobtavia uses a transformer like the original Octavia and the Maestro Brassmaster. What’s nice about the Bobtavia is its simplicity.…
Silicon Tone Bender
Here is a Silicon Tone Bender built around four BC109 transistors. It sounds pretty good! The original circuit was provided by user Mic Tester over at FreeStomboxes.org. I built this some years ago on a piece of strip board. I…
6 new PCBs from PCBWay
I got 6 new boards made at PCBWay.com. The PCBWay.com service is a great deal the biggest cost is shipping. The best deal is to order multiple boards at once since the shipping is combined. This time I waited til…
Parentheses Fuzz Noise
I built a few of PedalPCBs Parentheses Fuzz. great clone of the EarthQuaker Life Pedal. All of the pedals I built seem to have whistling noise/oscillation sound when the Gain and Octave are at 100%. I haven’t played an original…
Shiva Sonic
I received an email the other day from someone who had bought some pedals from me, it must have been 10 or 15 years ago! I was really happy to hear they were still using and enjoying them! The reason…
22/7 4069
First build of 2022! This is a 4069 version of RunOffGroove’s 22 The original uses the 4049 hex inverter. This the same circuit using the 4069. Both chips contain 6 inverters but the they differ in format and layout. The…
22/7 4069
Here is a version of RunOffGrooves 22/7 using the 4069. The original circuit uses the 4049 Hex inverter. The 4049 is a 16 pin dip with 6 inverters. Here is the 4049UBE data sheet. You can see it has 16…
