Ugly Face Build
build your own Ugly Face! Ugly Face is a racus squarewave guitar synth oscillator disguised as a fuzz pedal. Originally created by Tim Escobedo on his Circuit Snippets web page, it’s become a DIY classic. The ideas here are great…

Projects that I have built
Vulcan Build
The Vulcan is a heavy over to distortion by Joe Davisson. Check his Analog Alchemy page for more of his designs. Here’s a discussion of the circuit over at the DIYStompboxes forum. I created a PCB you can order at…
RunOffGroove 22/7 Build
Here is another 22/7 build. It’s a Big Muff variation. This unique circuit replaces the transistor stages of the classic Big Muff with CMOS inverters. It’s a unique flavor of Muff. CMOS inverters have their own unique flavor of distortion…
Haunting Mids Reflection
The goal of this project was to build three Haunting Mids, keep one and sell the other two, hopefully coming out ahead! This post covers the original Haunting Mids Fuzz. Note! This is not the JHS pedal with the same…
RunOffGroove UBE Screamer
This is another great RunOffGroove project. It’s a unique twist on the classic Ibanez Tube Screamer. The UBE Screamer replaces the op-amps and transistor stages in the Tube Screamer circuit with inverters from a 4049UBE hex inverter. I built this…
Boss Muff
I love Boss pedals, they are bomb proof, have a great form factor, work well, and look great. They don’t make a couple effects that I like. For example you can’t get a Big Muff in Boss. I had the…
Haunting Mids project
What’s Haunting Mids? Haunting Mids is a Big Muff variant. In a nutshell it’s the input buffer, and first two clipping stages from the regular Big Muff circuit. It drops the tone control and the output buffer of the original…
Work in progress
I always get into something for a while, then need to take a break. There are a few hobbies I always seem to come back to. Pedal making is one of these! I dug out a few of the boards…
22/7 on OSH Park
Built and test this second version of the 22/7 by RunOffGroove.com. Sounds good. This is a great alternative for Big Muff fans. The OSHPark project is public and verified. 22/7 is a Big Muff built around CMOS inverters in place…
UBE Screamer PCB v1.1
This is the second version of the UBE Screamer board. This version fixes a mistake with the reverse polarity diode. I’m calling this ready for public consumption and will add it to the OSH Park projects pages soon. The enclosure…
Super Frequency
The most fun DIY build you can make! This is my version of the Ugly Face Tim Escobedo. Great box with a unique sound . Not your typical fuzz or distortion box. Build your own from my OSH Park PCB…
UBE Screamer by RunOffGroove
This UBE Screamer by RunOffGroove.com is a unique twist on the venerable Ibanez Tube Screamer TS-808. It replaces the op-amps and transistor stages with a single hex inverter using an inverter in place of each op-amp and transistor. This has…
