Roland makes the AC-60 and AC-90 acoustic guitar/pa amps. They are stereo and have 2 x 6.5" speakers and EFX, but have less channels, are heavier and much more expensive. I'm somewhat surprised the CM-30's have sparked interest here. I wasn't interested until I ran into a returned-order pair at half price. They don't seem to be big sellers or on display at many places. Where do you find them; near the guitars or the sound room or the keyboard room? The guys at GC were not up to speed on them and were as surprised as I was about their power and features.

I'm sure if the CM-30 became a hit, Roland would consider a second generation step up. So, would we be looking at an 8 or 10" speaker and 60-100 watts? Seems doable, but the price goes to $350 and the weight to over 25 lbs. There are a lot of powered speakers out there to compete with THAT.

The CM-30 is a nice, compact unit. It's a great little amp that can be used as a mini-pa or stage monitor. I had a Boss MA-15 years back that was a wedge with a 5" speaker & 15 watts. For its time it was a great little portable thingy that I could use for monitoring (like a powered hot spot) or amping in tight spots. This is a few steps forward in the mini market.
