What is your overall opinion of this product?
It's light, four inputs (3 controlled with volume control knobs, one aux), with sound shaping and with batteries amazingly portable. While the sound isn't a $1000 amp, it is more than capable of holding it own in a large room. aspace battery cartridge is not available but its very easy and quick to replace all eight batteries. Takes alkaline and rechargeables. Perfect for practicing and small jam sessions. Works great with Ableton Live and Mainstage.
