The clean channel sounds nice and all of the Fender sims on the crunch channel sound nice as well. The high-gain amps are a little less convincing, but still good enough.
The various modulations are all ok, nothing special, only the plate setting is creating some "hiss".
All in all, for the money, this is very hard to beat, so if you are looking for a first budget amp, this is a very good option!
