Peach Fuzz Clone

This is a clone of the Frantone peach Fuzz. The signal chain is something like: In –> op-amp –> LM386 –> LM386 –> BMP Style Tone Control –> Out My first build sounded great but, I had forgotten the power…

Chips from Aliexpress

I bought a bunch of chips from Aliexpress. Are they legit? I don’t know, and I’m not sure how to check them. They seem to work. But, I’m using them in dirt boxes, if the sound is low fi and…

PWM by Tim Escobedo

I wonder what happened to Tim Escobedo? The author of Circuit Snippets, a page with a lot of great ideas for guitar effects. The site is no longer active, but it has been archived in a few places; here is…

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…

Ugly Face Circles

I made a few small updates to Ugly Face PCB. I needed to do a build to make sure that everything is working as it should. I ordered these boards from PCBWay.com. The service is a very reasonably priced which…

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.…

The Baron

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…

Ugly Face blue

A blue Ugly Face. I used PCBs from PCBWay.com and put everything into a blue powder-coated enclosure from Tayda. I wanted to put some blue knobs on this enclosure but didn’t have any on hand. I didn’t want to place…

Bobtavia analysis

This is a quick look at how the Bobtavia works. The Bobtavia is uses the LM386 to amplify the input signal. In the default setup the LM386 has a gain of 20. The output of the LM386 runs through a…

Bobtavia by Bob Starr

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.…

Fake op-amps

I bought some op-amps from Aliexpress a few days ago. They seem to be working. I patted myself on the back for getting a such a deal, they were about $0.08 each! All of the parts seem to be working…

Cheap parts from Aliexpress.com

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…
