Very versatile Amplifier.
This amp is perfectly suited for people who like to play different genres, so it's not just another metal-suited amplifier. My favourite feature has to be how the boost feature affects each of the four channels differently, so the boost on the clean channel is perfect for more funk, single-coil sounds while on the crunch channel, the boost helps give your tone a bit more volume/gain. The size of this amp could be great portability wise if someone wants to use this amp for gigs. My only complaint is the built in flanger effect as I can't dial the effect to a subtle enough level, but then I just use the built in chorus instead.

Versatile
Great practice amp or gigging amp. Built in red box, attenuator, and effects. Crisp cleans. Good crunch.

Better than the 36
End-all be-all of tube heads. I don't need anything else other than a tuner.

It's a "spiritual successor" to the Grandmeister deluxe, but is solid state amp instead of a tube/valve amp and features a few more tonal options such as the sagging control feature.
