A friend's brother (ex audio engineer at Bose) is behind this company, and they had a release party tonight not far from here at a studio in Somerville that I just got back from.
Their basic philosophy is that guitar pedals haven't really changed all that much since the 60s, so they're taking modern studio-grade electronics, using them to do things that people don't really expect from guitar pedals (for example, their bass OD blends a distorted and clean signal to give a much clearer low end than you'd expect from a distortion, while their guitar OD combines two separate gain circuits feeding into each other).
I'd love to tell you how the clean boost and the bass OD sounded, but honestly I never got past the Underdrive guitar OD. Holy shit that thing was awesome - Mike describes it as going from "slightly gritty clean to Led Zep," and while I'm sure part of it was the old Vox and Marshall head that I was demoing it through (with my Suhr - they encouraged people to show up with their own guitars if they wanted), it was just a killer sounding low to medium gain (maybe Tube Screamer-ish levels) overdrive.
Especially through that old Marshall head... I think the most impressive part was that it didn't really feel like it was doing all that much to the amp - it just sounded like the amp had a bit more gain on tap, at least with the pedal volume set to fairly neutral levels (cranking it could absolutely slam the front end, but I tend to not go for that sound as much). It was a killer, very amp-like overdrive. I want one - I've been looking for a good OD to take to blues jams and whatnot, and I'll need to try one with an amp I'm a little more familiar with and maybe with lower-output pickups than Rebel Yells just to be sure (though, even split it sounded pretty damned excellent), but it was a great-sounding pedal.
Video, but this doesn't really do it justice:
Hm. Do they have reverb and/or delay?
