I put together a Terrarium from PedalPCB. Terrarium is a DSP platform that uses the Daisy Seed by Electrosmith. The Daisy Seed is like an Arduino Nano on steroids with audio super powers. You can read the link above for a full run down of its features. Figure it’s a platform where you could build…
The Ugly Face is a classic DIY Stompbox build. Almost a rite of passage! The circuit, by Time Escobedo, has been around since late 2002! Here is my schematic. Schematic Parts List Part Number Value R1 1M (Tayda, Stompboxparts) R2 470 (Tayda, Stompboxparts) R3 100K (Tayda, Stompboxparts) R4 22k (Tayda, Stompboxparts) R5 1k (Tayda, Stompboxparts)…
Build your own Super Fuzz! The Super Fuzz is an octave fuzz used by Pete Townsend, Muddy Honey, J. Mascis and others. Read this post to learn more about the Super Fuzz. Build Your Super Fuzz Here is the schematic for the Super Fuzz. Note! There are several versions and schematics vary. This schematic matches…
The Flatline is a a great simple compressor designed by John Hollis. Check out my original article on Flatline for some background. This is an update to the original board that incorporates some mods by Atomium Amps. Besides me part value changes, this board adds a trim pot to set the release /decay time for…
I’m a big fan of the Tim Escobedo’s Ugly Face. This is a super fun project, sort of a. right of passage for DIY pedal makers. The sound is unique. The best way to describe it is as a square wave oscillator that hard syncs to the guitar signal. Since the output is either on…
I built a pair of Doboz VCO340 VCOs. These are based around the CEM3340 chip, which was used in Yamaha DX7, Prophet and other famous synths from the 80s. Here are my notes for the build for anyone interested in building these VCOs for themselves. The project comes as two PCBs and an aluminum front…
This is the Flatline compress by John Hollis with some mods by Atomium Amplification. I’ve built a few of these and they all work well. Flatline is a simple optical compressor built from a handful of easy to find parts. If you like compressors, want to build one yourself try this, you’ll probably like it.…
Small Time is a PT2399 based delay with tails by the Valve Wizard. Tails or trails if you’re not familiar allows the delay signal to continue after the effect is bypassed. Valve Wizard’s work is here. I saw the schematic and thought it looked pretty good and decided to make my own PCB. The first…
Thanks to everyone who came to the last pedal building workshop at Noisebridge. I was impressed with the enthusiasm! We demoed some pedals talked about populating the PCB and identifying the correct parts and placing them in the correct locations on the PCB and soldering. The next workshop is scheduled for Saturday, March 4th, 1…
The Tremolo Matic XXII (Tremolo 22) is a great sounding tremolo. This is origianlly from Stompboxology. I’ve written more about it here. I made a few changes to the original design. This latest version adds a few improvements to the first couple revisions. I have been manufacturing these boards with PCBWay.com. They have a great…
Small Time is a PT2399 delay designed by the Valve Wizard. This delay has tails. This allows the delay sound to continue after the pedal is bypassed. My first built worked well and wounded good. The tails was not as exciting as I thought it would but it is interesting and a small bonus. The…
Thanks to everyone that came to the pedal building workshop at Noisebridge. I’m writing this post as a follow up to help you all get your projects off to a good start. Get started Everyone should have left with a project to work on. If you don’t and need help finding an appropriate project contact…
