Battery powered eurorack
I had seen a lot of really cool eurorack in nature posts. Not sure if these were done live in the moment or put together in post production. The idea of twiddling knobs and making music at the beach or in the park was enticing. Let try and get you in the mood with some…

DS-1 Robert Keeley mods
I rehoused a few new circuits into some Boss enclosures last year. Boss Buzzbender Boss DRV Boss Muff I was left with some DS-1 PCBs. I have been rehousing these into 125B enclosures! It might seem a little crazy butI hate to let things go to waste. It might be good to have a DS-1…

PWM Build
I built another PWM. This is a a crazy noise maker. Almost more of a synth than guitar pedal. It has a great distortion sound but the output is extremely compressed, which makes it hard to use a band situation. That said the sound is unique! This circuit cam from Tim Escobedo’s Circuit Snippet website,…

Scuzz Box v1.1
This is a second version of the Distort-O-Matic XI from stompboxology. You can read about the first versions here, and here. Distort-o-matic XI is described as a distortion box with an aggressive tone control. In more concrete terms it’s a diode clipper and octave fuzz with with a two band active tone control 30db of…

New PCBs
I ordered some new PCBs. The boards from PCBWay.com are very reasonable but shipping can be costly, ganging orders together keeps the costs down. Whats was in this order? There were 8 different boards. Some were updates and other were new.

Flatline v1.1
The first version of my Flatline PCB worked well but had a couple of small problems. Check out my original post for more information about the Flatline Compressor. I fixed the issues with the original PCB, and had some boards made through PCBWay.com. The cost is only $5 for 10 boards, so it’s perfect for prototyping. The first…

Tremolo-Matic X build 3
This is a new revision of the Tremolo-Matic X from Stompboxology. You can read more about it here. In a nutshell, this tremolo splits the input signal into high pass and low pass filters and pans between the two. The sound is subtle and sweet. This type of tremolo was implemented with tubes in some Fender…

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…

Tremolo XXII v2.1
I updated this design again. It’s almost ready for production. In this revision, I improved the PCB layout by moving the components that make up the LFO to the left side of the board and the audio path to the right side; this meant I had to move the shape switch to the other side…
