Deformis update
I worked on Deformis, see my earlier post for details and schematic. In a nutshell Deformis is my version of Tim Escobedo’s Ugly Face in a wah shell with the pedal controlling the frequency sweep. In the first pass I got everything working but, it wasn’t working well. The biggest problem was the pedal action…

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

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…

Ugly Face PCB on PCBWay

I started by finding the PCBWay Eagle DRU file. This tells design rules that PCBWay will accept. This includes the minimum trace size…

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…

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 project or buy one of my builds from Reverb.

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…

Ugly face with tone control
The Ugly Face has an interesting set of options. The Threshold knob has to be the most interesting though least useful. Last year I thought I’d add a tone control in it’s place. I wanted to build an Ugly Face and keep it in 1590B sized box. This format makes it hard to fit more…

Building an Ugly Face
I built an Ugly Face last week and took some pictures. This uses the Ugly face PCB I made and the typical DIY stompbox parts. I used the alpha 12mm pots in a B sized box. The more common 16mm pots would also work.
