Sound
Let me start by saying that this is the second time I bought this unit. The first time I sold it because I needed money and because I had only one gripe with the unit. The problem was that I missed using my guitar in regards to volumes, feel and also the whammy bar. With the pickup system on the Gr-55 I would dive bomb and hit the pickup and the wail would just end. Also, even though the guitar models,amps,pedal effects etc are pretty good, they did not have the feel and complete sound I was akin to...those two reasons are why I sold it. Then I realized after a few gigs of playing out without the GR-55 that I really missed it. The reason I had to get it back is that the synth sounds on this thing are nothing short of awe inspiring. Add to that with the proper adjustment of the pickup and calibration menu (which will take some time to get right) the tracking is phenomenal compared to past relics. I use the piano,sax,harmonica,church bell, and other cool synth pads and bass effects that add a whole new dimension to our sound and the expression on peoples faces in the crowd add joy to having this gem. One more thing that I really missed was the thumb drive plug in which I utilze to its full potential by putting samples on it and adding them to our songs. For instance we play Children of the Grave by Sabbath and when it gets to the bridge I trigger Vincent Price doing the Thriller speech over the juggernaught sounding drums and guitar. There are so many things you can read more do with this great sounding unit that I can say literally I can't part with it.

Features
Like I said the USB thumb drive adds a great dimension to this unit, also it is great to load guitar backing tracks to the drive and then jam with sounds on the GR-55; it's like having the e-band and a synth in one! The addition of having two PCMS playing at once or controlling them in one patch with or without the guitar is great too. The only thing that I find this unit lacks is an XLR output and a dedicated guitar input to use the moldeled guitar tones to have a more authentic guitar feel and tone, but this is a synth unit so I have accepted that and bought the Eleven Rack to work that end of the spectrum and together they are the shiznit.

Ease of Use
It does take some time to understand the setup of custom sounds as you will find that you may have artiufacts from the preset that was installed if you do not go through everything and set it exactly as you want it. But, the presets are also a great place to start to get inspiration to build your sound and keep the paramaters of the patch. Just expect to take some time getting used to the interface and jumping back and forth through menus quite often. I have not tried the librian so I don't know if that is an easier alternative, but all in all I could not think of a btter way of making the unit more user friendly.

Quality
I did have an issue with the first units GK-3 pickup on the A pickup where it would be faint at times and also there is a screw that hides the wires to the GK-3 that came out on the first one and it was lost. The second unit had the same problem with the screw, so I used some locktite to take care of that. Besides those two issues it is built strong and holds up well for live use.

Value
I think this is a great value for everything you get. So much so that I bought it again even after losing money on the sale of the first one
