Well I just listened to clips of the Mini and the Beta. IMO, the BB does a much better job of all out distortion than the Mini, and it seems much simpler to use. The Beta however, sounded awesome! It kinda reminded me of the El Oso in the ToneFactor clip. At least in the higher register. But all the other demos I've heard of the El Oso and from my own personal experience of trying it out, I really don't think it's one that I'd like too much. Now I might have to go for the Beta eventually.
