On paper, this sounds like a great amp. It seems to have a great wattage-to-weight ratio for a combo (200w:44lbs). Plus it's a wedge shape and can even be specifically used as a powered monitor...even has side-handles. And its got a 12" in there, which some aren't keen on but many think is a great compromise between 10's and 15's. Anybody tried one yet? I would love to hear what you thought! Thanks P.S. Anyone know if you have to disconnect the internal speaker when using an extension cab??
