Feature:
This is why unless you're touring, there's no sense going for a MEsa triple rectified head. The AVT has great features; four foot switchable channels, scoop switch, bright switch and great built in delay. There's a lot of built in reverb which is great but to me the built in effects are all about the great delay. I'm turning in my Boss digital delay pedal. Its useless now. Also, the emulated line outs are great for stereo recording to your PC. Headphone jack for silent practice is aweosme too. To get these features at the price is great.

Quality:
Give me abreak. This thing is a tank.

Value:
Again, no other way to get the tube sound with features for this price.

Desirability:
Great looking amp. From someone that grew up watching Judas Priest and their wall of Marshalls, its kind of cool to look over at it and see the gold Marshall plate staring back at me.

Sound:
All four channels are excellent. The OD-2 really rocks. With the scoop switch engaged you can really get a nice metal rhythm sound going. For leads I use the OD-2 channel without the scoop switch and use a boss cs-2 compressor/sustainer and the tone is great. I would defy anyone to close their eyes and tell me an all tube amp is better sounding than this. Great amp. I will say that at very high volumes I'm hearing a little muddiness on the rhythm but I just haven't tweaked it yet. Anytime I've been unhappy with the sound it was easily changed by tweaking the knobs.

Support:
No rating. Haven't had to deal with anyone

Overall:
I will have this amp for a long time. Again, Mesa is great. And tubes are great when they are in both stages, pre and power, but this amp does a great job of mimicing that with just the tube in the one stage. And unless you're on tour, you don't need anything other than this Marhsall. You can play it silently with headphones. you can play it at low volume in your bedroom or you can gig with it.

I love this amp! I auditioned a lot of other amps before buying this one. I especially love the TONE and the effects. Don't let anyone tell you that you can't get great tone from an AVT, because you can. In my opinion, the clean tone from this amp is better than their tube amps. Plus, you can get great high-gain and distortion sounds without deafening yourself and everyone around you. A GREAT club amp! I highly recommend it!

Feature:
good features, but needs presence/contour controls for each channel. It has master presence and volume and no contour.

Quality:
I'll be frank- i abuse my amps. But this one holds up nicely. the birch is really solid (and a bit heavy). If you want a portable amp this is not the on for you unless your a monster like me and can carry its kind of weight everywhere. The knobs are also holding up perfectly. The only bad part is that the cover tears really easily. Mine already has a few duck tape patches on it, and I'm pretty careful with the covers.

Value:
Fortunately, it doesn't need much work, and it's really hard to find four channel amps especially with effects. but theres no use for the acoustic simulation- tis crap. go for a 3 channel amp like a marshall, save a buck, and get great support and bone-crushing tone. Still, if you want a Marshall and can't afford the mode four, this is the way to go, and for a Marshall like it, it's a great deal (then again marshall is way overpriced...). I got mine for 720 though.

Desirability:
It's a great looking amp, sounds good, and has a bunch of unique features, its just bit heavy. That's the one thing I'll hand to Marshall is that they make sexy amps.

Sound:
great clean tone, but acooustic simulation is far from realistic and both completely lack volume. Distortion sounds good, but you'd expect more out of a Marshall, and it doesnt't sound lie 150 watts- more like 100. effects are limited but good, however all 16 are pretty similar. At the same though, it ofers a multitude of great sounds and the scoop feature is really nice. I use it with a mexican strat and itll scream when i need it too. And, if i remember correctly its got celestion 70-80s in it.

Support:
Marshall ofers absolutely no support without self-paid long distance calls with 20 minutes of waiting or overseas mailing. They have absolutely no American based service offices, and no repair options. If there's a factory defect you'll have to pay huge shipping fees overseas for their mistake, so I don't reccomend buying this product online as yoyu can't check it. Also, when I called them up about a problem with mine, they lied and said it wasn't covered in the warranty, then said I couldn't fix it myself or I'd void the precious thing which was useless anyway. I fixed it myself in 5 minutes, saved 200 bucks, voided know warranty, and lost like 5 bucks with the phone call.

Overall:
I love the amp, but it leaves me wanting, and for a while it's great, but isn't the 150 watt monster you think it is. For me though, it's been a god amp, and I've played a lot of shows with it and don't plan on having to buy another any time soon. Also, the fact that it uses solid state amplification and a tube preamp means virtually nothing to replace. It's pretty maintenace free if you're into that.
