The sound that comes out of this little box is splendid. Great jazz tones with smooth highs and tight lows, probably the best clean tone I've had and very portable and lightweight.
But there is a major downside: the amp is very noisy. The new ones don't have the fan noise problem but there is a lot of hiss coming from the amp. More than I ever had with any other amp. This means that recording with this amp at low volumes is not possible (both with a mic or with the xlr out): the hiss is just overwhelming. The phones out has this enormous amout of hiss as well, making it annoying to use.
Therefore, FORGET about recording with this amp mic'ed.
Volume wise, this little amp can gig. I used it with a 5 piece jazz band yesterday (with a semi-loud drummer) and I had it on 12 o'clock volume. This is about the maximum you can go without clipping, but this is common among most amps.
The reverb is usable as well but has modulation which may not be everyone's cup of tea.
Overall, very disappointed about the white noise issue (I've since trying another little jazz and a jazz 12 and the problem is consistent) but it's the only problem I can think of.
