Made a few enclosure for some new projects today.

This is a a second build of Distort-O-Matic XI from Stompboxology. Read more about the first version of the project here and here, and a demo. The first version of the PCB had a couple mistakes which I fixed with this board. I designed the board to fit a 1590B enclosure. In the first build…

I just got this Roland Go Mixer Pro. It’s a small (about the size of your hand) mixer that connects to several instruments and microphones to your phone. I got mine used on Reverb.com for $125. I like buying used gear. It’s usually cheaper and saves waste. What’s it good for? Recording with your phone,…

Made a little progress on the Doboz VCO340 today. Check out my previous post for more info about the VCO340. Tl;dr it’s an 8hp VCO based on the CEM 3340. i’m working on two at the moment.

Second build of the “Uber Drive”. This is clone of Paul Cochran’s Timmy overdrive. Maybe this needs a better name? I manufactured these boards over at PCBWay.com. Their prototyping service gives you 10 boards for $5. Which is a great deal. It also left me with a few boards to spare so I thought I…

Soldered up a few boards the other day. Here are four of the new boards, a Silicon Tone Bender, and another Flatline compressor.

Just received some new PCBs. I ordered these from PCBWay.com. The quality was excellent. The cost is very reasonable These were about $1 per board with shipping. Ganging orders together saves on shipping! A few couple updates and a couple new things this time. Small Time is a PT2399 based delays with trails by the…

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…

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…

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…

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…

The Doboz VCO340 is a DIY VCO built around the CEM3340. This is a VCO on a chip that was used in many famous synthesizers back in the 80s. Here’s what the Electric Druid has to say: The 3340 is the oscillator chip found in many of the famous polysynths of the analog era; the…
