    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 built. This version makes a few changes to the original. The original uses an LM386…

    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 470 (Tayda, Stompboxparts) R3 100K (Tayda, Stompboxparts) R4 22k (Tayda, Stompboxparts) R5 1k (Tayda, Stompboxparts)…

    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 makes them great for prototyping. I soldered up the board. This time I used a…

    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. That said the sound is unique! This circuit cam from Tim Escobedo’s Circuit Snippet website,…

    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 get milled. I had to pull those out of the original SVG image, make a…

    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 an order for four knobs. Looking through my parts bin, I found these pink aluminum…

    PWM demo

    This is a demo of Tim Escobedo’s PWM. see my build page for more info about this circuit: http://www.super-freq.com/tim-escobedo-pwm-pcb-build/ 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 Escobedo is sort of an anomaly. He contributed an amazing collection of ideas vis his…

    Tim Escobedo’s PWM

    Tim Escobedo was this wildly creative force in the early DIY Stomp Box community. His circuit snippets page was had a lot of really great ideas. One of the ideas there was the PWM, which stands for pulse Width Modulation. This circuit converts your input signal into a square wave and varies the amount of…

    Super Frequency

    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 mid 2000s if I recall. It’s a unique circuit with a surprising sound if you…

    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 and inventive there are a lot of building blocks. Out of all of these the…

    Ugly Face on OSH Park

    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 synthesizer than fuzz pedal. It produces square output from the input guitar signal. You can…
