Feature:
It came with drivers and a Cakewalk CD (but only works on Windows machines - there was no mention of this on the web-site.) Also came with a nice, long power-adaptor. The transformer is in-line, so there's no wall-wart. That was a nice idea. And there are two 1.5Watt speakers built in! Too cool. Yeah, they sound thin (they are 2" speakers...) but it's great to play around with.

Quality:
Well made and well thought out. It's made for desk-top use, and in that application I can't see it ever breaking.

Value:
The GS-10 is well worth the money I paid. It all boils down to "useability." I'll use this for many things for years to come.

Desirability:
How much kitchier can you get? A great effects box with built in speakers! Too cool. I can see millions of young guitarists finally being able to practice at reasonable volumes without the neighbours complaining.

Sound:
I had the GT-6 and the ME-50 before this. I found the GT-6 to be very thin-sounding and lack-lustre. The GS-10 fixed that problem and sounds huge and warm! The amp and speaker emulations are Boss's best yet, and the effects are just as good as the ME-50. Here's one peeve I have - the GS-10 does reverb, but it has no Spring reverb. For a dedicated guitar processor this seems to be an odd ommision. The other 'verbs are pretty good considering the price. One great feature I feel is worth mentioning is the Tremolo. The ME-50's trem had a square wave type of sound - on/off/on/off/on... etc. The GS-10 has a control that lets you choose how steep/harsh the cutoff will be. This makes it very useful to get the old, Fendery trem as well as special fx type trems.

Support:
I've never had a Roland or Boss product break or stop working, so I've never needed customer support.

Overall:
This is going to be a much-used piece of gear for years and years. Even as a practice amp this thing is great - practice with all the best effects, etc. I'd likely get a TC Electronic G-Force for it's non-overdriven sounds, but for Distortion and Overdrive I suspect that I'll stick with the GS-10 for some time to come.

Value:
Editor is great...Flawless in Mac OSX

Desirability:
Built well/Looks good

Sound:
"10" would be a nicely mic'ed tube amp...

Support:
Not sure

Overall:
A VERY overlooked piece in the industry and/or market...
