Sound — 10
I tested it with a Tokai Love Rock with stock pickups and it sounded wonderful. I would recommend this amp mainly for blues -> classic rock players and all points inbetween, with a boost it could probably hit 80's metal (Metallica & such) but I didn't try it. This amp is really just 5W of Marshall roar, I got the chance to crank it up to full volume and was blown away by just how loud it was. It starts to break up at around 4/5 on the volume knob giving you a fair amount of headroom on such a small amp. The cleans on it sounded very nice as well very glassy Marshall cleans.
Overall Impression — 9
For playing rock this amp is amazing, the classic Marshall tone really shines through. I compared it to a Blackstar HT-5 and while the Blackstar is good for metal and has more features, I'd still buy the Marshall. I'd be on the way to get the Blackstar and somehow end up in a store handing over the money for the Marshall because of it's amazing tone.
Reliability & Durability — 5
I couldn't really comment as I haven't played it for too long but it seemed very solidly built and there's not much that could go wrong with it. (The 5 is just a random number since I don't know what it should be) but from my experience with Marshalls I would imagine it's a pretty reliable solidly built amp.
Features — 3
Features wise this amp has very little. It's a one trick pony, but it's trick is sounding good. All it has to offer is bass, middle & treble controls, the on/off Switch and an input jack. Simplicity at it's best. The lack of a master volume control is the only thing that would really put me off this amp.
