Deformis – Ugly Face with a mix control

Here is an updated post with a schematic and parts for the Deformis. This started as Tim Escobedo’s Ugly Face. I made a few changes. I swapped the LM386 with a dual op-amp. The 386 was used in the Ugly Face as an amplifier with a gain of 200, a single op-amp can easily replace that. The second op-amp was used as a mixer. To mix the signal from the first op-amp with the square wave produced by the 555, which is the output of the original effect.
