Ugly Face 1.1

Working on making PCBs with Kicad and SMD components. I went to my go to project the Ugly Face by Tim Escobedo. What ever happened to Tim Escobedo? I took the original Ugly Face with a couple value changes and…

Fugly Face

A few fur covered Ugly Face clones. This circuit is so much fun. It really needs an update. Ideas coming soon!

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 The site is no longer active, but it has been archived in a few places; here is…

Super Frequency

This is my spin on Tim Escobedo’s Ugly Face. The original is a great DIY project anyone that hasn’t built it should give it a try. Super fun, unique sound, parts are easy to get, and it’s not a difficult…

Ugly Face 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…

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.…

Ugly Face black with dots

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…

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…

PWM demo

This is a demo of Tim Escobedo’s PWM. see my build page for more info about this circuit: Here is another song demo where the PWM was used on one track in the mix.

Tim Escobedo PWM PCB build

The PWM b Tim Escobedo shapes your guitar signal into a variable duty square wave. This is staple of synthesizers. Known as pulse width modulation or PWM. The sound is supper compressed fuzz. This circuit is a simple build. Tim…
