this auction.
Modifications via the auction:
"- installed custom faceplate
- use of extremely rare, original Roland BA662A VCA to further increase this unit's claim as one of the most authentic TB-303 clones available
- bass boost mod
- filter modulation (VCO acts as modulation source, waveshape controlled by a three-pole switch to choose from square, saw, or off; modulation amount controlled by a designated potentiometer)
- envelope amount modifications (increased range controlled by a 2-pole switch)
- filter cutoff range modification (allows the filter cutoff to reach lower frequencies than would be otherwise possible)
- installation of custom EvilX0X 0.5 firmware, which, among other things, implements swing, "pattern nudge," use of real-time pattern end-points, etc. See this page for more details.
- a supposed mod to increase the grit in the sound by overtaxing the power supply, although this mod, when engaged, does not appear to affect the sound at all"
There's an audio sample of the unit on the auction page. I mirrored it
here for when it goes away.
