The amp is really solid and pretty loud. So, if you don't want to bother your neigbours, you have to keep the volume down. The volume knob, however, is sensible enough to have a nice control so you can chose easily the level you want.
The gain of the dirty channel is very felxible, so the amp can space from a slight crunch type of sound to an heavilly distorted metal-like sound.
The only problem i found with the common eq for the clean and dirty channel is that, when you turn up the volume, there is an enormous quantity of low-end frequencies that come out in the dirty one, so in theese cases, in my opinion, you can't use easily both channels without touching the eq.
The spring reverb is good and easily controllable.
The chromatic tuner is basic and intuitive.
The simulated headphones output is somehow brighter than the cone out (at low volumes), but the sound is still good so you can use it to record with a soundcard.
The manual says that the clean channel can naturally break up at higher volumes, but without a wattage control or a master volume it's just too loud for any bedroom or "practice amp" situation.
