I bought one of these at Long and McQuade last week as I was really impressed by the sound, the power, and the portability. It's a 200 watt combo amp with a 12 inch speaker + tweeter and weighs only 25 pounds. I had no trouble at a jam session with a drummer, 2 guitars, and vocals. I would definitely take it on gigs (although PA support would probably be needed in a larger venue). The tweeter can be turned on/off. It has a cool feature called "low expander" which reduces the mids and extends the lows and sounds really good. I looked a the Carvin MB combos but our lousy exchange rate plus shipping costs nixed that idea. I also considered the Traynor SB110, which is even lighter than mine, but it has less power so I decided it wouldn't have the required volume. Traynor is Canadian so many of you have likely never seen it. If you should come across it definitely check it out. It's good quality and ruggedly built. I have other Traynor/Yorkville gear: my 2 x 10 cab sounds great and I also have the Yorkville SR 300 reference amplifier + studio monitors.
