Inspired by all the positive talk on the B1500 and looking for a reasonably lightweight, reasonably powerful and reasonably priced head I took the plunge on a "scratch&dent" B800 on ebay direct from Carvin. I think it must have been a 10-day return because there was no scratching or denting I could find on it at all. My two primary rigs over the last couple years were a BBE Bmax SS into a Carvin DCM-1000 power amp or a Yamaha BBT-500H head (occasionally with the DCM-1000 slaved from it). Cabs are 2 Avatar B112s (the 18x18x15 rear ported ones) and one Avatar SB-112. The cabs are 8 Ohm (although I had a period where they were 4 Ohm, the B112s with Neo drivers). Physical impressions: While it lists with a shipping weight of 22 lbs it feels significantly lighter than the 25lb DCM1K (but also noticeably heavier than the ~12lb BBT-500H). It is light enough that it's easy to carry and has fairly large, sturdy rubber circle feet on both the bottom and the side opposite the strap handle. It stands easily over the strap handle on the B112 cabs. The knobs feel sturdy and turn smoothly. Detents would be nice. The switches (for mute, active/passive, effects loop) are also solid but the labels are hidden from view by the top edge of the case if you are close and/or above the amp. Getting the footswitch took care of this problem Sonic Impressions: The "base" sound with the drive down is very clean and quick. Reminiscent of the BBE Bmax which I like (but found "too clean" or maybe lacking/covering a touch of snap/sparkle/edge lately). The drive seems to add presence in the Sansamp BBDI/RBI sense of the world. It adds a nice edge to the sound for loud rock settings. I'm a "leave the EQ flat" kind of guy and this amp works for me that way. With my quieter acoustic group I leave the drive down for a cleaner sound and with my loud rock group I push the drive up for edge/bite to make my presence known. Misc Stuff: Did a small festival gig with it in a small auditorium type of setting and it had plenty of oomph on its own with 2 12s The soundman used the DI out (with separate level control) at that gig (not that it was needed) and got a good level and sound My SB-2 (a very, very high output passive bass) could not get the input clip light to light up in passive mode so the input seems to have lots of headroom I could get the output clip light to light up with both my SB-2 and Rumblefish PJ with the input in passive mode and moderate drive levels Conclusion: I'm really liking this head. It seems to have the right amount of power for my needs and is light enough that I don't mind carting it around. I like its sound a lot and it has pretty much all the features I could want. The only things I'd add are rackability (or some kind of protection for the knobs) and an effects blend or series/parallel option. So you folks who wanted me to keep you in mind for when I passed it on - you'll have to wait a while. I'll get some pics of it eventually but don't have any right now but it fits very nicely on my Avatar 12s where a standard rack would hang over the sides.
