Peach Pit

This is my take on the Frantone Peach Fuzz. Peach Fuzz is an op-amp buffer into a pair of LM386 in series, followed by a tone control similar to the Big Muff. It uses a dual op-amp but only one…

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…

This is my second entry in the End of Days Fuzz Challenge! The idea was to build a circuit similar to the Proco Rat replacing the LM308 with the LM386. The LM308 is a single op-amp the LM386 is an…

Bobtavia is an old-school DIY octave fuzz. It’s a lot like the Roger Meyer Octavia but uses an LM386 instead of transistors. The Bobtavia uses a transformer like the original Octavia and the Maestro Brassmaster. What’s nice about the Bobtavia is its simplicity.…

I need some op-amps, usually I’m buying these from Tayda Electronics or StompboxParts.com. Tayda is the cheaper of the two but StompboxParts ships faster. In this case neither place had all of what I wanted in stock. I wasn’t in…

I made some ugly face PCBs back in 2009 and had a couple left over. I built this up when I first got the mill. The Ugly Face is a DIY classic invented byTim Escobedo way back in the early…

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…

Just published the Ugly Face v 1.1 to OSH Park. Built and tested, it works well! This is classic DIY project, it’s almost a rite of passage for new DIY stomp box enthusiasts. The Ugly Face is more of a…
I’ve playing around with the 386 Audio Amplifier. This is a really great chip. It has a lot of possibilities. Looking at all of the great circuits that use this I’ve noticed there are many different ways to set the…
