Feature:
Features galore. CD in Jack is killer, as mentioned, especially for plugging in your electric acoustic, or for running a second guitar in through an offboard preamp. Also great for plugging in a metronome for practice. The emulated out is cool, but actually sounds a little muddy to my ears, but not bad. The amp sounds so good at reasonable volume levels out of the matching cab, I would probably just mic the cab instead of using the direct outs, but direct outs are always handy. Great to have a headphone jack on an amp. A desireble feature for the married man who tends to irritate the wife with squealing pinch harmonics constantly.

Quality:
QUality appears to be solid, but I have not abused these things for years to create on objective opinion. The fact that it uses power ICs instead of tubes lends itself to much higher durability by design alone. Plus, maintenence is ZERO except for maybe a few scratchy pots every 5 years or so?

Value:
Sounds good at a fraction of the cost of any tube amps and alot of solid state amps.

Desirability:
Black and Gold, standard Marshall looks. Good to Go.

Sound:
I am a hardcore tone tweaker. I have a ton of gear and I am always experimenting with different preamp, power, and cab options. I currently own a Triple Rectofier, A Marshall DSL50, and a rack of tube preamps, modelers and tube power amps. All this searching for really just about 3 or 4 "perfect" sounds. I play Les Pauls ( a standard and a studio) and a Highway One strat. I received the MG15DFX as a christmas present and at first, I would not even open the box thinking it was not a serious piece of gear. But since it was a present, I started using it a little, to my extreme surprise, I was blown away at how good it sounded. Now the little MG goes everywhere I need to practice and even with all my tube rigs sitting in the same room, I often just sit down and plug into that to practice. For a long time, I thought, sure, it sounds good at 15 watts, but this series would never be good for a live situation. Then I was in a music store one day and plugged into a MG100HDFX and matching cab. Once again, I was completely blown away and how great this sounded. I was amazed. Suddenly, I felt like a fool having bought into the whole "if it isn't a tube amp, it is junk" philosiphy. Even worse, I have an custom tube amp on order to the tune of about 2 grand. The MG100HDFX sounds absolutely wonderful for the price. The CD input is perfect for plugging your electric/acoustic into if you have acoustic parts during your set which my band does. These things are great. Now, they might not have the projection and tube drive required for stadiums or arenas, but how many reviewers out there, or those reading reviews are playing arenas? The important thing is if the amp sounds good for your needs, at your volume level, for your audience. This amp is an A+ for all of these requirements for me. The only possible improvement would be the cabinet and speakers, but you would have to study very close and find a speaker that match the same frequency response - in other words, don't play this head through Vintage 30s and think it will sound better. It likely will not. I think the MG speakers are relatively flat in thier response and most of the EQ is in the head itself, so higher quality speakers with the same response would be the ticket. Like Eminence man o wars or maybe tonkers? Anyway, this amp is righteous, and if you a texas blues man looking for some stellar SRV style tone, to me, this rig sounds better than a Fender with a tube screamer in front of it. The onboard reverb also sounds way better than my Boss RV-5. Love it. I was a fool to overlook the MG series as merely a "beginner" series of amps for so long. I will own one soon. THis is the best soundig solid state amp for tone, projection, and delievery I have ever played through. The only current production solid state head in the same ball park that I am aware of to to a comparison on would be the new Randall G3 series and in the first 10 seconds the Marshall wins because the Randall emits so much noise it is not usable. The Marshall is very quiet except for when you go to very, very high gain levels, and even then, it emits less than half of the noise the Randall does.

Ease of Use:
Very easy to use, the only thing that would make it more "perfect" would be to make the "modes" footswitchable as well, like from Clean to Crunch on channel 1. The DSL also suffers from this shortcoming. If this is the magic amp for you though, it might be worth having it professionally modified to have these footswitchable.

Support:
No real opinion, though I have contacted Marshall for technical questions in the past and was happy.

Overall:
Love it. Ample Power, decent delivery (great delivery with medium and low gain) Awesome.

Feature:
The product didnt come with any extra accessories. I really like the emulated line out and the cd input. The crunch feature sounds AMAZING. The effects could be slightly better, but overall the components are fine

Quality:
I've only had this for 11 days now and its already taken a fall but its working great. When i got it everything was fine and still is. It seems quite dependable, and is VERY appropriate for use on the road.

Value:
THIS IS WORTH ITS VALUE

Desirability:
I've wanted one of these since i started playing guitar...it rocks

Sound:
The sounds is the normal sound you get with a marshall amp. The qaulity is quite good, with a pedal running through it however, you sometimes get some buzzing and such. It is exactly the sound i was looking for and is quite compatible with my music style (punk and rock for the most part). The amp on its own sounds great. I also have a boss ds-1 and that too sounds wonderful running through it. Overall it is just what i was looking for and exactly what i thought it would be....AWESOME

Ease of Use:
This is VERY easy to use. The directions are quite clear. The only thing really needed to run this is your eyes. Just read and everything will work. LOL....

Overall:
As long as it works

Feature:
least usefull features is the foot swith,cant select clean to crunch,or od1 to od2 also cant program individual effects,hard going playing live.

Quality:
overall quality good, no worry about it packing up,and yes gig with it {kicks some serious arse}

Desirability:
sex appeal full stack looks cool on stage

Sound:
the clean channel not a bad sound od1 a little tame, od2 great sound(kicks but}.

Ease of Use:
easy to use , good sounds but i have to run chorus , delay , through effects loop,comp,sustain through front guitar input sounds great.

Support:
never had a need to contact manufacturers

Overall:
will not be surching for any other product in the future, this thing is perfect

Feature:
All that you would expect and then some. foot-switch included

Quality:
Damn near indestructible. Have had for 9 yrs and although it is now a back-up to a back-up, If called upon I know it will work.

Value:
Since it is SS, It is brittle and sterile but with this comes the value of SS electronics. Reliable and uncomplicated

Desirability:
Timeless Marshall Appearance. But not Tube so this gets it a lower score.

Sound:
I owned this head for many years and never was that impressed. played a band battle once and met a guy who ran his through a 1960A cab and the difference was night and day. Learned that day the importance of great speakers. My sounded weak with the matched cab. Also I recommend using pod 2.0 in effects return. Set this up right and you have a tone that will be envious. But out of the box with matched cab, it is nothing at all special. And once you add the pod and good cab you well over 1,200 but it is incredibly reliable solid state design.

Ease of Use:
no mystery just fiddle with knobs and rock out.

Support:
Korg has great cust support. Needed replacement pot that broke off and was sent one even though i was not a unregistered user.

Overall:
A great Beginner to Novice half stack. Highly recommend getting good cab with it because it helps so much and also when you do upgrade to that JCM/MESA/BUGERA/SOLDANO, etc... you won't have to buy the cabs you already have them.

Feature:
Channel switching with a foot pedal and enough built in effects to make it sound passable for gigging, which for a transistor amp is excellent.

Quality:
The fan/heat sink module looks like it came out of a computer. And I have always had those fans go bad on me in computers. They sure as heck could have put that transistor on a bigger heat sink and leave out the fan that if it quits the heat sink is sealed inside the amp so no air flow! I took the amp out and put it in an old Marshall head and turned the heat sink one rotation so if the fan quits the air flow will go UP and hopefully be enough to keep things stable. Now the amp is completely open on top and doesn't get hot. There goes any warranty tho. What's really cool is the amp will fit in the bottom of a Plexi style Marshall head because the transformer is mostly inside the amp not hanging down like most transistor amps. I found an old long box 30" Marshall head (empty) and it fit perfecly.

Value:
I think they cost $100 too much compared to other brands. If you must use a transistor head, try them all and see which one you like. But you must play them against a loud backup like a band situation to really know what an amp sounds like. There really is no way to "try out" an amp in a store.

Desirability:
It's a usable transistor amp, as good or better as any other. If you know how to MAKE your setup sound decent with a proven sounding guitar and a pedal setup you know how to use, you can gig with this amp.

Sound:
It's one of the best sounding transistor amps. I have many amps to compare and if you use a healthy professional guitar you will get giggable sounds from this amp without using a pedal. Depending on the pickups in the guitar I can get country twang/surfin' sounds. If I use a double humbucker I get a real healthy rock with plenty of full tone, plenty of bass, mid and treble, however to me the amp sounds best with the bass and mid all the way up and the treble all the way off. It's got a fuzzy/buzzy distortion if you turn the gain and treble up too much but if you keep it just barely up on gain it sounds very good. My rating is for transistor amps, not comparing it to tube amps, there isn't a comparison to tube amps they sound quite different. It's a very good sounding amp that will get by very well with the audience however it won't fool the tube guru, but I always wondered why the big mouths out there aren't working somewhere.

Support:
Don't know.

Overall:
I will use it until it blows and then not buy one again, just because I have quite a few other amps already.

Feature:
footswitch all cables you need and power plug

Quality:
very sturdy put togetehr by pros

Sound:
it has the awesome warmth that you would normally find in a tube amp and has all the extras to get that tone you dream of especially with the reverb od 1 and od 2 come as standard i got it with the avt 412 cabinet sounds much better than the mg cab without any hiss i found that if you use mg head with mg cab you get a very bad hiss when turned loud so i suggest to anyone spend 90 bucks more to get what you deserve!

Feature:
The Footswitch could have more settings, like with the digital effects...Its hard to dial the amount of effect u want during a gig.

Quality:
Marshall has to be the best

Value:
For the sound, size, and effects, this amp is almost like a half stack

Desirability:
I own one. Its never let me down on any show. It goes great with pedals of any kind.

Sound:
This amp has a True Marshall sound.The Digital setting for a model tube amp sounds better used than without. If your're looking for a true Marhsall sound and that legend distortion, this is the amp for you.

Ease of Use:
Over-all the sound is great. It plays well for any kind of music. Perfect sound for metal, but forgiving on the clean channel, meant for good melodic playing.

Support:
Haven't had a problem yet, but I've heard the nobs break easily.

Overall:
Can't get better than this

needs spring reverb and it would kick ass.
it seams like it will last forever though. I compared it to a 50 watt tube amp, the avt50 i think it is, and the tube stile had a better clean.

I bought this product while ago, and at first I didn't think that it was going to sound good with the AVT412a (200 Watts, celestions). I bought both products anyways and let me tell ya, it sounds awesome .

Feature:
Effects will stumble occasinally, not 100% reliable. Otherwise, sounds good, effects are good if not having a "moment". If you like people looking at you funny and asking "what was that", then get this head. For home use however, it's fine, more than enough to get you voted off the island for too much noise!

Quality:
OK, I give it a crap rating here for 2 things. First the cables that came with it were junk and soon failed. Second, the fan soon started making a loud buzzing when first turned on. I shot a little WD40 on it and it stopped making noises, I do believe it will fail at some point so I'll replace the fan before (hopefully) it quits and the amp burns up.

Value:
Good value even with issues.

Desirability:
It has Marshall name, that is what gets you to buy it. Marshall has a reputation that is unbeatable. Watch it though, Marshall, this one has issues!

Sound:
Good overall, it does seem to have a glitch occasionally, itdoesn't completely cutout, it just has a "moment"? I've seen this in other reviews. If you want a Marshall head, this is the cheapest way to get there. After a couple years I would advise players to save a little longer and go up a model or two. You can't beat all tube heads for classic rock tone.

Ease of Use:
Not rocket science....but, what does that mean anyway?

Support:
Don't know, I tend to fix things myself and I wouldn't have wanted anymore junky cables or another crappy fan anyway.

Overall:
It's good for my purposes (home use), but I can see that it would be a good gig item if you aren't worried about a glitch once in a while. Or, if your a young person on a budget and want that Marshall name on stage behind you.
