Feature:
Must get a midi foot controller if you use it for giging. (I got the berringer one with the dual cc foot pedals so I could assign one to wah or other effect while having one dedicated to volume. The global settings feature makes this easy to do. I lkie the meter function too, you can select main out, sub out etc. set the level for each patch and they are right on the same volume when you switch banks. The PC editor is great (especially for old time knob turnners like me)

Quality:
Haven't had it long enough to know about lasting quality but there are no loose parts or scratches.

Value:
I had to go for a ten...yeah it's high priced but getting this many cool sounding effect one at a time would cost a lot more and be a whole lot more trouble to keep up with

Desirability:
Technically speaking it's a must have.

Sound:
I honestly believe this unit will come very close to reproducing almost any recorded guitar sound in existance. The only weak spot would be the wah. Not that it sounds bad, it sounds good but, not quite up to the Vox or Morley.

Ease of Use:
It's pretty easy (I currently had no midi experence) I had some cool sounds and the foot controller going in 2 hours. Hook up the PC editor and it gets even eaiser

Support:
Not really delt with Boss but, roland has been good to me so I suspect since they are the parent company Boss would be the same

Overall:
Never seen a unit with this many good sounding effects this easy to use for this kind of money

Feature:
Great software and set-up very well. The additional librarian makes it very easy to shuffle patches around especially when you're using over 200 patches. Also works great with the FC-200 pedal.

Quality:
built like a tank. Been to Europe with it a few times already and hasn't failed me.

Value:
can't beat it for the price.

Desirability:
love the blue lights!!! Isn't that sexy?

Sound:
this is one flexible unit. I switched over from Intellifex products mainly because of the ease of use of this product. but I've fallen in love with the sound because it's set up so well and with enough work, you can get any sound you want with great warmth.

Ease of Use:
very easy to set up and use. Software makes it that much easier.

Support:
Roland/Boss isn't my favorite company when it comes to support. The couple of times I've called them, it seems I know more about it than they do. Sounds like they have one guy giving advice for 10 different products. But not a big deal considering it's ease of use and the online forums.

Overall:
just a great all around product.
