This is an audio demo of the Distort-o-matic XI from Stompboxology. Check out my build page for a schematic and images of the finished project.
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…
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…
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…
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…
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…
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…
I wanted to create a project in a pedal with a treadle. My first thought was to get a couple of used Dunlop Cry Baby’s. It looks like these were going for a low price of $40 on Reverb.com. With shipping pushing the price above $60, it was a little too expensive. Wah Pedals on Reverb.com I…
I have more than a few projects in the works at the moment, thanks PCBWay! To get caught up, I’m going assembly line. I sat down and soldered all the resistors in all of the boards, then diodes, trimmers, sockets, caps, and transistors. Soldering all of the resistors and diodes in every board, at the same…
This pedal sounds so good I had to make another! Check out my first build and the build page. I manufactured these boards at PCBWay.com. This board is posted at the PCBWay Shared service. You can order and build it for I milled a gray powder-coated enclosure. It looked better than I was expecting. It’s got a…
I have a few new projects in the works. I’m doing this batch sort of assembly line style. I soldered all of the boards, now I’m milling and drilling all of the enclosures.
A new patch of boards. Some improvements of previous PCBs and a couple new things. I had these manufactured at PCBWay.com. When I’m done finalizing the designs and tested everything I’ll post these to the PCBWay Shared service.
