Deformis update
I worked on Deformis, see my earlier post for details and schematic. In a nutshell Deformis is my version of Tim Escobedo’s Ugly Face in a wah shell with the pedal controlling the frequency sweep. In the first pass I got everything working but, it wasn’t working well. The biggest problem was the pedal action…

Doboz VCO340 knobs
While I wait on parts to build this I experimented with some knobs to get an idea of what the finished device will look like. My parts are back ordered until November. The Doboz VCO340 is a an 8hp VCO built around the CEM3340 chip. My plan is to build a pair of these for…

Ugly Face Circles
I made a few small updates to Ugly Face PCB. I needed to do a build to make sure that everything is working as it should. I ordered these boards from PCBWay.com. The service is a very reasonably priced which makes them great for prototyping. I soldered up the board. This time I used a…

Summon Fuzz a bigger muff
This is Mic Tester’s 21st Century Big Muff. Its the standard big at it’s heart but updated. It uses an op-amp for the input and output stages, a James tone stack, and adds an interesting gain control to the clipping stages along with a diode lift switch for the first stage. I’m a Big Muff…

Building wah enclosures
I wrote about buying some bare wah shells earlier here. I started assembling them for a project. Here are some notes for anyone else trying these. If you’re going to paint or do any type of finishing work, you should do that before going through all of the assembly process. It would be difficult to…

Titan Boost 2
Here’s another Titan Boost. This is a John Hollis project, you can read more about it here. In a nutshell, it’s a clean boost with an output signal up to 30v peak to peak! That’s a big boost! The circuit is simple, easy to build, and runs on 9 volts without a charge pump. It works by…

Elktronics Fuzz Build
This PCB came from Elktronics. It’s fuzz similar to the fuzz face and Tonebender built around the CA3046/3086 transistor array. Here’s a demo: The board came with all of the surface mount parts in place. I needed to add the two box caps, the two glass diodes, and the CA3046. I put a socket in…
