it's pretty good value for what it is.. very loud, lots of tone shaping, tuner and compressor on-board. Does lack a bit of punch and definition you'll get with more expensive combo's/heads-cabs!
Had mine a couple of years now, it's performed well.. Mine gets carted along and does a decent job any time I don't need to go collect my main rig.
I use it mainly as a practice amp at home (very nice sounding headphone and aux ) Would I buy one again, don't think so, but then I love to swap and change gear.
I thought it was the best out there for the money at the time I bought it.
I'd give it a 7-10 on my scale
