The versatile SA-300 is built to handle any type of audio source you plug into it: microphones, rhythm machines, keyboards, CD players, etc. With full-range, high-quality stereo 2.1 channel sound, sturdy construction, built-in effects, advanced anti-feedback control, two-piece transportability, loads of I/O options, and more, the SA-300 is a traveling musician's dream.
Feature: Biggest feature: light weight. I don't like to lug around heavy equipment, and each of the two components of this amp weighs less than 30 pounds.
Quality: Good quality, absolutely no problems in over one year, gigging about twice a week.
Value: Well, it is expensive!! If you are on a budget, you might choose more weight/less cost.
Sound: Stereo separation is modest, but I find it effective for reproducing the stereo samples in digital pianos. Plenty of power for the small restaurant/coffee house venues I play in.
Ease of Use: Pretty standard controls, easy to use.
Support: I haven't needed support.
Overall: I would like better stereo separation, but this unit is adequate for my purposes.
