Overall amp sounds good with one major flaw (at least for me) - it lacks decent low end. So for overdrive it is very good, for strumming it is quite good too but it does poor job for more melodic music because low E string sounds very tight and lacks extension to the bass, so not so good for clean tones.
Bass knob has no effect from the middle position and it looks like that hardware just cuts low end intentionally - you cant add more bass with pedals too, if you pass music to line in it is filtered too - low end just erased. Headphones emulated output produces the same sound - without decent low end.
Pros
* decent build quality
* nice tremble and middle tones
* nice overdrive sound
Cons
* thin clean tone because very weak low end
Overall, it would be ideal amp, for home, if only it had more punch in low end. For me it is deal breaker because most of the time I use clean tones.
