Feature:
It has everyhthing I need or want but does not have features I know others may like (such as a master volume) so I have to give it a 9.

Quality:
I have to give it a 8 becuase the first one I recieved had no functional reverb. Otherwise perfect which is why I can overlook the QC issue with the first head.

Value:
For a Marshall half stack with this sound quality I say it is worth every penny.

Desirability:
It's a Marshall.

Sound:
This amp IS all that-at least for me. Cabinet sounds fantastic. I say that out nof the box. I can get just about any desired tone out of this machine. From classic blues to hard rock/heavy metal to thrash. There seem to be limitless combinations for tone. Very happy with it.

Ease of Use:
Not much to it. 1 equilizer, 2 channels, clean, classic crunch, lead 1 (very distorted) and lead 2 (distored distortion so to speak). Bass and trebel boosters as well. All channels can be tweaked a long way using the eq and boosters and gain.

Support:
I was shipped a new head before I sent back the defective head. No questions. Didn't miss a beat (don't need reverb much although I like it).

Overall:
Great stack covers just about any genre!
