It's a dedicated all-in-one guitar amp.

Whereas audiophile amps are primarily concerned with avoiding distortion, a guitar amp embraces it.

With the pre-amplifier switched off, the guitar may be played through a traditional guitar amp.

It eliminates the ear high levels needed to capture the natural sounding distortion and overdrive, produced by the speaker of a loud guitar amp.

A slightly different method of distortion creates a fuzzy sound by replicating the sound of an old worn out guitar amp.
