It still sounds like a 50 watt plexi on the clean channel(basically what it is), I have it on Class A on the back rotary knob, which helps it from peeling the paint off the walls

It's a 2 channel Amp, but the Gain Boost acts as a 3rd channel for metal distortion and leads

A decent overdrive pedal into the clean channel is all you really need, and the reverb sound good, too
