The BA-330, like other similar Roland products, has amazing volume for its size, weight and price. I don't care if it's actually 3 watts, 30 or 300. All I know is it is/can be loud. Just as I cannot explain how or why the Bose Compact sounds the way it does, I can't tell you how Roland does it either. All I know for sure is that both of these amps do a very good job of filling a room of 100 people +/-.

I'm sure there are 20 or so other amps out there that can do the job to someone's satisfaction. I gave two positive opinions of two good amps. I hope my opinions were helpful to someone, as many of yours have been throughtout the years.

@Gary, I didn't understand why you were commenting to me. Did I say something wrong... or right?
