I had one but not for long, ended up selling after about a week. When they say its based on the OBP-3 circuitry they weren't kidding. Since I already had an OBP on my bass it was pretty redundant. The AGC gave a nice overdriven tube sound but I never used it. So for me there was no justification for keeping it. There was nothing at all wrong with the product. I think it's great for people who want keep their bass passive and/or need a little added flexibility on a DI. Overall I went back to my presonus tubepre for recording and live until I got the presonus Studio channel. There was a bunch of hype over these that died out kind of quickly but I think they do well in the small DI/preamp market at least better than the sansamp for me. But as far as the sound pretty much everything you hear about the OBP's apply ei. clean, seem to liven the tone, usable eq, and the sweepable mids are nice. The AGC was kind of just a bonus to play around with for me.
