This is Midfi Electronics “Random Number Generator”. It’s a radical fuzz that adds oscillation notes that randomly arpeggiate off of the fundamental note played. Crazy noise maker pedal. I’ve built several of these now by request. The owner of the design over at Midfi was gracious enough to share the schematic on the DIYstompboxes forum which is why I want to make it clear that this is NOT my design, and if you get one for me you are strictly paying me to make a clone since these aren’t available anymore.
This is the first one of these I’ve built. I added the mods of changing a 100k resistor with a pot, and a diode that is switched into the circuit, but quite frankly they don’t do a whole lot. Any others of these I build will just have the volume knob as original intended.
The Uglyface effect is an oscillation based distortion/fuzz pedal with envelope controller designed by Tim Escobedo. It can do a wide varitey of off the wall sounds (laser guns, bagpipes, drones), and it has many different ways to modify the circuit. I’ll liked it so much I built it into one of my old junker guitars (details below).
This is the first Uglyface I’ve built. I built it into some crazy electronics box with huge heatsyncs on the sides. Seemed to fit the circuit some how lol. I did the standard controls of Volume, Threshold, Frequency, and Sensitivity, and added a mix control that worked ok.
I had this old guitar knocking around for a while, so I decided to mount an Uglyface inside of it. It has all the same controls as the pedal above, but I also added a Light Sensor with switch for controlling the frequency knob.
Been a while since I added to, or even updated this site, even though I’m still working. I recently built two Midfi Random Number Generator clones, and circuit bent a VL-tone. Here’s some rough pics. Hope to get some more content, and maybe even some revamping of the site soon.
