Feature:
this amp features 16 digital effects i only use the reverb/chorus one and it sounds great. it has 2 overdrive channells i use the first one as i aint a big heavy metal fan and a really lovely clean sound.

Quality:
heavy duty. it could hold in the worst conditions like my shed for example lol.

Value:
worth the 900 big ones especially for a big time brand.

Desirability:
i personally dont lyk the look of the front pannel jusf how the volume knobs are placed but the old saying goes, ugly on the outside beutifle on the inside.

Sound:
top quality rich sound. clear on everything marshall ahve done a great job. could be louder though. there is a bit of comp between the marshall avt100x and the fender 65r. sounds awsome with my monterey lp copy.

Ease of Use:
very simple to use. pretty heavy if buying i recommend gettin wheels for it, if buying.

Support:
i dont no anything about the support but i hav read a lot of reviews before and it is marshall were talking. top quality stuff. famous bands use them so the support must be excellent.

Overall:
very satisfied there are a few probs about it 1- could be louder but thats just me talking, 2-front panel could look better, 3- to heavy, but all amps are like that lol but all in all 1 great amp i love it and i am going to have it for a few years. recomended for the band thats about to get into gigs. suitable for gyms, halls, audotoriums and large audotoriums. and anything smaller then them. also great for the good old practice jams in the garage.

Feature:
My only complaint with the features is that it should have seperate EQ for each OD channel.

Quality:
Its a Marshall so its top quality, espeacially for the price.

Value:
Absolutley worth the $630, I've never played an amp in this price range that sounds this good. This amp blows away any fender, line 6, or VOX in its price range.

Desirability:
After playing this amp in the store I'm definatley getting one. The hyrbid tube/solidstate is awesome. The pre amp circuit is simply genious. The two OD channels are also very nice.

Sound:
Amazing overdrive, You can get an insane crunch similar to that of a cranked JCM 800. Loud enough to gig out of, even the 50 watt model

Ease of Use:
This amp is very easy to operate, clean and simple.

Support:
The amp is backed for 3 years so the support is pretty good.

Overall:
This amp covers all of my needs, incredible overdrive tones, loud enough to gig with, and its affordable. I'm going to be using this amp til I start playing Huge venues. This is really all you need to play at a small to medium sized club.
