Feature:
I love that it has a presence on it. With many modern amps there're are no presence. It just helps you get the right pinch you need. Also the detail and body is real nice, it gives you the ability to shape your distortion into that perfect vintage sound.

Quality:
Don't really know. Never had one, just used one. Marshall has always had great durable amps. You could bash an MG on the ground and it would still work.

Value:
Its worth paying for instead of buying an even more expensive replica vintage amp. You can get the same sound at a lower price and even have an added Modern sound.

Desirability:
Its just so darn sexy with its smooth sleak lines and crisp sound. If I won the lotery I would be in the store buying it the second I got my money.

Sound:
Amazing vintage sound and the reverb is perfect. You can get the right Jimmy hendrix or Jimmy Page sound with it. The modern sound is also amazing for that hard rock sound you want. Its mostly the vintage sound I used.

Ease of Use:
Easy to use. No complicated knobs or settings. Just turn it on and play around till you get that perfect sound.

Support:
Never used it, never needed it, and they keep it that way.

Overall:
This Amp would last me a long time. It looks sexy, it sounds sexy, it is sexy.
