Feature:
The greatest thing about this amp is the autostore effects. Gain and volume are a plus for each effect.

Quality:
Product is made very well with the musician in mind. 100 watts you can carry in one hand. My friend has another brand that is 100 watts also but has head and 4 speaker cabinet. I will be practicing before he gets his out of the van. I don't hesitate to take this amp anywhere from a 25 person bar to a 5000 person outdoor ampitheater. If theres anything I don't like about this amp, I haven't found it yet.

Value:
Trust me I shop around. For the price I paid, it was a great deal compared to others in this price range. Some were the price of this one and had only two channels.

Desirability:
The effects have a certain appeal as far as wanting/needing a new amp. As far as 'sex appeal'..well you know a amp is a amp. I never had a chick say 'Hey I'll go out with you because you have a Hughes and Kettner and not a Fender'. I'd say it was a practical addition.

Sound:
The sound is incredible overall. The clean channel leaves a little to be desired in my opinion, but will get by on.

Ease of Use:
Setting the amp was easy. It comes with a quick guide, or you can set it to your personal taste. The thing I love about this amp is the ease to switch sounds back and forth. I went from playing the 'Star Spangled Banner' on the warp effect, to 'To Late For Love' on the crunch effect, to 'Black Betty' on the lead effect, to 'Amie' on the clean drive and never touched a single knob on the amp.

Support:
I haven't personally had any trouble with this amp. I did visit their website, and the warranty with this amp seems fair enough.

Overall:
I will play it until it falls apart which should be many years. The on board effects should be all I will ever need. If this amp gets stolen or destroyed, I'd buy another just like it. This amp compares and goes beyond others I considered. The only thing I wish I knew before hand was how much fun this amp is to use. I'd bought it sooner. The most thing I love about this amp is the ease of switching sounds with the greatest of ease.
