Just got mine in the other day
Dirt looks way more green in the picture then it actually is
Solid quality- bolted knobs, nice and long power cables, came with M3 and M2.5 screws which was nice.
ERD is definitely a distortion, sounds real nice with some resonance or other harmonically rich signal behind it. And being able to patch it out is really cool- through skin has a really unique sound, and varying pressure has a cool response. Also tried a halloween gummy, had an effect sort of like a low pass filter, opening up if the cables moved closer together in the gummy. Although it does seem to need a buffered stage after it or it attenuates like mad which is a bit odd.
SIR is, in practice, an evolving 8 bit stepped voltage generator. Interesting chaotic behaviour. It will almost be a pattern, but will always be just a bit different. CV does give it some good life.
Still playing, but I like em!
