via the listing: "This is a modified MS-20 VCF built to handle a 9V power supply. I built this to use with keyboards or noisemakers that didn't have a tweakable filter! I was going to buy a Frostwave clone but the ridiculous prices people are paying for them forced me into this, and now I have to regrettably clean house a bit. Built on stripboard!"

Update: the circuits are based on Tim Escobedo's clone posted here.

Uglyface, Tremulus Lune and DOD440 in a box

YouTube via Dovinia
"This is a multieffects unit consisting of an Uglyface (oscillator/fuzz), a Tremulus Lune (tremolo) and a modified DOD 440 Envelope Filter. It sounds quite terrible, but that's the whole point. While the soundquality is rather abyssmal, things may get somewhat more interesting if it is played in stereo; Try adding "&fmt=18" at the end of the url."

The Uglyface is by Tim Escobedo. When available you can find them on Ebay here.
The Tremulus Lune is by 4ms. You can find some 4ms pedals on Ebay here and at Big City Music.
