Feature:
Simplicity at it's finest. Clean channel sounds good, reverb (depth) is very well done. Easy to operate. Simply a solid amp.

Quality:
I hate to keep rating everything a 10, but this thing appears to have no faults (for me.) Construction, fit and finish, quality of components all = top notch.

Value:
For the price you can't beat it. It is plenty loud, easy to use, well made, and has that great MArshall sound -- for $500. Top that.

Desirability:
It's a Marshall. Nothing else to add.

Sound:
Amazing. Took it out of the box, rolled the knobs up and plugged in. I play it through a Marshall 1922 2x12 cabinet, and it sounds fantastic. Great job Marshall. It has that warm tight distortion that is classic Marshall. If you play Megadeth, slap a pedal on it for extra boost. If you play anything else, this is your amp.

Support:
Haven't had to deal with them. I doubt I will.

Overall:
Best but out there in this range. Period. I could not be happier.

Quality:
The quality of this product is pretty good. I don't think this product will break any time soon, but you have to be very, very carful with it. It's definately "road worthy."

Desirability:
This product is very hot. It looks "pure Marshall," and it's sure to get the eyebrows raise on all your friends.

Sound:
This sound is the best-of-the-best quality. It sounds very professional and chrunchy. If you want that pure chrunch sound this is definately the head for you. But whatever you do, DO NOT BUY THE MG100! If you want to, just wait until you have the money to buy the AVT 50H. It is definately worth the up-grade. You could also just put this head with the MG cabinate substituting the MG100 with the AVT 50H.

Overall:
Simply awsome!

Nice and loud for 50 watts. Pretty good distortion. Needs more than one output jack so you can stereo link another cabinet but not on this head. Would recommend to anyone as a pratice head or small gig head, not quite enough power for a full band unless you play quiet music.

This amp does have a valve in it; it is in the preamp section of the clean channel, so the clean channel acts and sounds like a tube amp, because it is. The overdrive is nice and thick when gain is at 10; it is dirty and compressed when gain is at 4. This is a quite versatile amp. i am at odds with the cabinet I have -- it does not contain a decent Celestion speaker. Once i get a Celestion stocked cab, this amp should sound even better. I do wish it had the digital effects on board -- you have to step up to 150 watts (I can't see anyone needing more than 50 -- this thing is quite loud) to get the effects. This is a great deal, though.

Feature:
what this lacks in features gives back in Kick ass Marshall Tone..

Sound:
I set off to a guitar store originally to try out some amps you know , i really needed a head so i tryed peavey ibanez crate..nothing that really caught my ear then i figured hey i wonder how expsensive those marshalls over there in the corner are. Well I saw the avt50 and it was cheap. AS soon as i played i knew it was for me. I had the volume at 2 and it was too loud for the store.. The manager told me to turn it down ahaha . Makes a guitar sould like it should. Can wait to get it!

Feature:
Would have liked the onboard effects like the AVT150, but didn't need the extra hundered watts. Judging from how great this amp sounds, I'd guess that the onboard effects are awesome. The Reverb on this amp is very functional.

Quality:
The amp is rock solid. Well built, and looks excellent as well. Did I mention how great it sounds !!!!

Value:
The AVT50H is a great deal for anybody who really wants the experience of owning a Marshall.

Sound:
This is a fantastic sounding amp for the price. It's a perfect amp for home/studio recording purposes because it's great sounding at any volume. On stage, the amps usually get mic'ed anyway, so if the amp sounds great mic'ed in the studio, it's pretty much going to sound that way live.
