From what I've gathered so far, it's the Eric Bolvin signature model, which I didn't know existed. I still have yet to hear about how they play, but I did find one on Ebay, and they can be purchased from Eric Bolvin's site,
www.bolvinmusic.com. I like some of the ideas associated with it, and I've been considering experimenting with a deeper cup, but it almost sounds like it might be a bit too much.
