Feature:
I don't know what to say here. It's best feature is it doesn't have many. It's just a pure old time tube amp. The effects send/return can be switched out of the circuit and that is a new feature for this model.

Quality:
I don't really know, I'm not an electronics engineer. It probably isn't the very best in the world, but it sounds great, looks great, and people recognize this amp as a true ICON in the business.

Value:
The price didn't go up in the US, the US dollar was devalued by about 40%.

Desirability:
It's like knowing you have a proper foundation to build upon. It's an amp everyone should have the opportunity to play to measure the sound of their own amp. I bought it for it's sound.

Sound:
I don't think a bad sound can get through this amp. (I don't mean it will help bad playing or cover up bad playing.) It loves effects pedals and they do NOT come through fuzzy/buzzy. Don't try this if you love the amp you have, it will break up that relationship. It sounds so nice you won't miss reverb, it doesn't have it remember. It really is all that people say it is and it is good to have so I don't go thinking my transistor amps sound so hot. Be careful, this amp will change your ears.

Support:
The support in the UK is incredible, don't know about the States. I hear bad things about support in the States, but no experience there.

Overall:
I'll never sell it. If lost, stolen, or wrecked, I'd have to look for a used one, I got this for $500 less than the usual discounted price.

Feature:
the amp by itself is good enough for me.

Quality:
-good quality-

Value:
it's good, but a vox ac30 is about $600 cheaper with about the same quality

Desirability:
it's prctically the amp of the 70's- u can't resist it

Sound:
really smooth warm marshall sound, especially when cranked really loud. could use a marshall power brake. it breaks up real nicely.

Ease of Use:
it's a lot easier than the old ones to get distortion from.as i said.... the marshall power brake u may need.

Support:
pretty easy 2 reach-

Overall:
it's tha only amp u'll ever need

Feature:
It's simple, plug and play, there aren't a bazillion knobs to mess with so you'll hear the true tone and not a generic one.

Quality:
It's a marshall.. need i say more?

Value:
You get what you pay for...

Desirability:
Vintage = Sexy

Sound:
Awsome tone, i love it and i'll never part with it and, not to mention, it's LOUD for being a 50 watt head. Ahh the sound of an all tube head... it's music to my ears!

Overall:
Its great!!! If you are looking for a great, rocking head that is simple to use... this is it!!! you can experiment with patching the inputs to get different tones...

Feature:
Like another person said this head's best feature is that it has little. No knobs to get in the way of the sound you want. I would recomend using a good Reverb pedal though.

Quality:
This head will last you a life time.

Value:
For the sound it gives you its a steal.

Desirability:
Marshall Plexi's in low light or concert lighting. Thats the end of other wanna be stacks. We all know what the women say when they see a Plexi.

Sound:
If you just cant live without that classic rock and B.B. King sound then this is a must have. Combined with a Gibson 59 Standard Reissue there is nothing you cant do. The 1987X and the 1959SLP are basicly the same just more power. I like the 50 watts because you get the famous crunch at lower volumes.

Support:
Marshall or your dealer will do what ever it takes to fix anything. Not that it will ever break to begin with.

Overall:
I am going to buy the one ive been playing for months. Trust me when I say if you want "The Tone" the search stops here.
