Feature:
IT IS NOT A WALL-WART!!! I was so happy that a company actually had the brains to make an adaptor that has an extended cable, because they know that home recording studios are often cramped for space on the power strip. It makes me feel like they were thinking ahead. There are so many little hidden features on this thing it really amazes me still and I've had mine for about a month. Built in tuner, 2 effect processors, the battery power option, direct record out, the mic-in and line-in essentially turn it into a 3-channel powered mixer with a guitar amp and a couple of effect pedals (6 total but only 2 at a time) and a tuner, noise gate, and a D.I. all thrown into one little box. That is cool.

Quality:
This thing seems solid. I can tell the company wants to have a reputation for being high quality gear, instead of some janky ghetto rig that you worry will break. I'm not worried at all. If I pay twice as much as another amp I want to be pretty reassured that my little box won't die easily. They did a good job.

Value:
It is nice. But it is expensive compared to other amps this size. If you are just looking for a cheap practice amp you are better off going for something simpler. With this, you are paying extra because of the tuner, the effects, the mic mixer, the possible battery power, the amp modelling record out, etc. etc. If you just want to plug in and blast I would suggest one of those little Peaveys or something similar for half the price. If you want a package that does an awful lot more then this thing shines. I love mine. But yeah, it is a bit on the expensive side for a little amp.

Desirability:
Its compact, it does a LOT, it's portable, it's nice and neat and to the point looking. I picked this out of a wall of little practice amps as the only one I would be willing to buy. The mic-in was what sold me. And it really sounds good. This is not some 'gain+vol+low+hi' generic amp. I can play this anywhere AND have a mic to sing at the same time if I want to. It's louder than you think it would be when you crank it and it doesn't get all muddy when it's all the way up. All of these things make it a sexy little box. I have a fetish for compact gear that has more than one application though so maybe my judgement is a bit slanted.

Sound:
It is really responsive to your picking strength even at low volumes. It is WAY louder than I thought it would be when I turned it all the way up. It doesn't lose quality that I have noticed even at the lowest or highest volumes. It has a noise gate that you can turn on or off too so you can be really loud on it and not hear any fuzz in the background. I usually use my zoom pedal for tone and just go clean, but I have just plugged direct into it and chugged around with the metal and insane channels just for laughs. You would be surprised how loud ths thing is for its size. The mic input doesn't change with the guitar model you choose, it is just clean, so essentially you are getting a free mini-mixer with it. I am not into the 'insane' sound other than for goofing off with metal riffs for laughs, but it is pretty versatile if that is your thing. The direct record out is a very nice touch if you do your work in headphones or through a computer, because it can sound like it is a huge guitar amp on a recording with all the modeling, without actually waking up your neighbors.

Ease of Use:
It's an amp, dude. It ain't rocket science. There are a couple of tricky things, like the extra uses for the 'tap' button, or how to save a sound setting (it has 4 memory slots you can save your own settings for) that I had to check the manual for, but other than that you just plug it in, turn it up, and it automatically adjusts the EQ to the sound model you picked if you want it to. Yeah it's pretty easy.

Support:
They have a website where people post new sound settings and ideas for audio for it. I only browsed it once, but it's nice that it's there. I haven't had to use the warranty or call for help so I don't really know regarding that.

Overall:
I cannot give it a 10 here because it is pretty expensive for a little amp. However, you do get what you pay for. It is way ahead of other practice amps because of all the extra features. The 'record out' jack for instance for direct recording, the mic mixer, line-in, programmable settings, battery option, non-wallwart adapter, extra effects, tuner... all that stuff. It is durable, it is small, it is loud, and it has all these little added stuff. classy, but pricey.
