so far, so good.


I play in a rock trio. The amp is powerful, clean and satisfactory. I play left hand bass, and the bottom end sounds great. Horn produces clear highs. The effects may not be used much, time will tell. For the money, portability, sound, I have been pleased. Reliability is unknown at this point.
