Feature:
Would like to see a "presence" control in the eq, but it is sufficient "as is"

Quality:
Aesthetically, THE BEST ("Marshall look"). Solidly built. Have not had a problem in my 1 year of ownership

Value:
A bit pricey, no doubt, but worth it for "the Marshall sound" Just bought my second one: one for home, one for work. Both times i tested the MG30dfx (cheaper) and both times this little 20 watt job blew the 30dfx out of the water!

Desirability:
I've always been attracted to the "Marshall mystique" ONLY play Gibsons through this baby; NOTHING sweeter than a Gibson through a Marshall--a match made in Heaven. Thank you God!

Sound:
The tube (valve) preamp section gives one "the real deal" not "sounds like" or "mimics" Also, REALLY gets LOUD. Compared it to the MG30dfx (30 watts) and the latter was blown out of the water

Support:
Don't know; haven't had to deal with, hope not to, so i rated it "neutral"

Feature:
Single channel with push button to overdrive. If it came with 30 watts, a 12 inch Greenback and footswitch I would gladly pay more and this is all I would use.

Sound:
Very good authentic Marshall valve tones. Super crunch and lead tones with a great bluesy bite on clean.

Feature:
It has all the usual stuff like OD/Clean switch, gain, master volume, 3-band EQ, plus reverb but only one channel. Some people would appreciate a footswitch but I can mostly control distortion level and tone with my guitar.

Quality:
When it works it works, but I've had the fuse blow twice on this thing with no apparent cause (well obviously there were too many amps but you know what I mean.) I didn't do anything strenuous to it to make it break, just bedroom playing. I wouldn't dream to think of what would happen if it was bashed about a bit during a gig or in transport.

Value:
I would like it a lot more if I knew that it would work each time I turned it on. I haven't had it for a year yet and most of that time it was in a techy's storage space for things on his to-do list. Now it's broken again.

Desirability:
It seems like a good piece of marketing - they say it sounds just like real tubes, but cheaper, got the Marshall name, looks a bit boring, but that's the Marshall look.

Sound:
Well, it sounds pretty good, nice and much clearer than modeling amps and such. Very verstile but some might say it doesn't have enough gain. I play blues, classic rock so for me it's got more than enough gain but for metal and similar styles it probably won't do it.

Support:
Well, it's broken twice so I've had some experience with this. The first time I had it repaired the techy took his sweet time fixing it (like five months) but Marshall got everything sorted pretty quickly when the guy finally got around to doing something.

Overall:
I've not really been satisfied with it for very long at all because it keeps breaking. I am considering buying a different amp instead of getting it repaired. It sounds nice when it works but that it not often for me.

I played this amp in the store for two hours before purchasing it. In the store I was able to turn it up louder than I would have been able to in my apartment- I was able to get about a dozen different and distinct usable tones out of the amp by adjusting its two channels and their gain and volume knobs. The clean channel sounds very warm, the distortion channel goes very loud. A very good 12 inch speaker amp certainly.

Feature:
The AVT system that mimics tube amps is quite impressive, even at low volumes. It needs a footswitch (at least as an optional piece). It really doesn't HAVE many features (and honestly, a chorus or delay or SOMETHING built in for the list price would be nice. At is very straight forth. Only a separate reverb swith. Is that a feature?

Quality:
I see nothing wrong with it's construction. Quiet, tight, and good tone. Classic Marshall in a tiny little box.

Value:
Retail is a little high, unless you NEED that Marshall sound (which I decided I do), in which case, you need it. Amp sounds very nice for what it is. I DO think however a few more features at the price-point would be nice. If you don't need it to sound like a Marshall, you could get more for your money. But then again, it wouldn't sound like a Marshall

Desirability:
It's little, but you know what they say! It ain't the size of the wand, it's the magic it contains. (And whoever said that had a little Marshall...)

Sound:
If all you expect is a small "Power Amp" to play along with the CD and get your licks down in your den, and you don't expect it to fill up an auditorium, this is not a bad amp at all. You could record off of this amp, and it wouldn't sound bad. I am "borrowing" one from a friend to use to see if I like it and ultimately buy it from him. The speaker could be bigger, but again, it isn't poor by any means. An excellent practice amp. Reverb isn't great.

Support:
Not Applicable. I can download the manual from the website. That's about the extent of my questions or needs so far...

Overall:
Nice little practice amp. Great sound. If you can live the price, and the lack of features, it IS a cool little amp. I don't think I can find a 20watter that sounds like this one, but you pay for that convenience.
