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,…
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 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.…
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…
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…
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…
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…
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…
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…
Here is another Big muff. I had these boards manufactured at PCBWay.com. The idea was to make a Big Muff PCB that could be used to easily build any version of the standard Big Muff. The board has an on…
Here is a build of the Morbid Fur fuzz. There were a few errors in my first version of this PCB. All my fault. I had these boards manufactured at PCBWay. com. They do great work and have many options…
Here are two more Haunting Mids fuzz. These came out pretty good. Check out the project page you can order PCBs from OSH Park and build your own! This is a great sounding Big Variant. It’s unique in that it…
