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.

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.

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...) read more but it's great to play around with.

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

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.

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

The Wow Factor
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.

Musical Style:
Blues, art-rock, neo-baroque minimalism
