I have the Carvin BX500 as a back up to my GK 1001 RB and Traynor YBA 200. It does hold its own with the GK but of course not as warm as the Traynor 200 watt all tube. Definitely worth the money. I am going to try and run it at 2 ohms with a 4 ohm Schroeder cabinet with 2 15s and a newer fender 8 ohm cabinet with a 250 watt Fender 12 inch for a gig next week. Tried it at home and seems fine. Lots of tweaking available on the Carvin which is good for the different acoustics we encounter in small bars and not running the bass through the pa.I had a BX500 for a while, which I mostly used as a backup, but the former owner wanted to trade something rare for it that I kind of wanted back, so we did that. IME the BX500 held it's own with a GK 1001RB-II surprising well in a side by side comparison. It would definitely do bright and tight quite well, and I preferred it in at least some ways to my HD350, all in all. I'd be sure to buy new, and make sure you understand Carvin's warranty and service policies.
