This tube amp has different preamp settings that emulate different amp types, from a clean channel modeled off of a bass amp, to bluesy crunch channels, to rock channels from four different eras. The four cleaner channels particularly have a bite to them that is spectacular. Even though it doesn't have a metal setting, its modern rock channel works very well. The only flaw I see in it is that harmonics on the wound strings sound muddy. But overall, it has an impeccable sound.
