Quality:
This product is great as far as make, but it IS made of PLASTIC! I'm worried about breaking the pickup while moving the instrument about, but I'm always careful and don't plan on letting anyone else handle it, so I figure that if I trust myself with it, then it'll be fine. I might take this on the road with me, but I would need people to be extremely careful.

Desirability:
It's ugly.... Plain, flat out ugly. Makes my mandolin look like a machine. BUT, it's very fancy-technical looking, so it'll make you look smart, considering that you'll be able to tell them that you installed it yourself! The GR 20 though is very subtle. It's not flashy, so you won't get ladies (or guys, I guess) with it, but if you make it work right on stage, then you shouldn't have any problems in that area after all. Besides, a musician isn't the appearance of his gear, but the quality of his musical performance.

Sound:
This product has great sounds, most of which are extremely versatile. As said in other reviews, the guitar sounds lack (some of the "guitar" sounds are actually rather sad). But otherwise, it's all good. I put this product through a Line 6 DL4 for looping, and it works perfectly. I've even managed to compose some simple songs at this point, and I've only had it for a few days now.

Ease of Use:
The GR 20 was a challenge to attach. It also doesn't help that I am using it on an electric (four string) mandolin, not guitar. So I had to spend more time making sure that the pickups lined up with the strings. The sounds are great, the surfing is ver intuitive (as long as you follow the patch lists in the manual, but that's a given). The manual(s) were very clear about installation of the pickup and making the machine function.

Feature:
least useful - setting up/installing the pickup on my Ibanez Artcore semi-hollow body electric guitar. This took the most time and I had to go to a local hardware store and buy additional double sided tape.

Quality:
Plastic main unit, not a 'hard rocker' stage pedal, but studio use should be ok but i wouldn't want to drop it...

Value:
Not until it tracks better, I use it as a substitute for a real bass on my own recordings (direct into the board) and even the slowest tempo playing whole notes, well, it would be nice to hear what I play 'when' I play it and not a half second later...

Desirability:
Fix the latency & pickup install problems...

Sound:
Lots of ideas can be had/inspired by the sounds a guitarist can now get.

Support:
it would be nice if Roland/Boss had a proper forum it's users could get info from. My one question about the terrible tracking problem was an answer along the lines of 'adjust my playing & attack to get rid of the latency..."

Overall:
See above, no I wouldn't buy a new one unless i could try it out (a new model/pickup) at the store. Great sounds that a non-key/synth player like me can definately use but again, see above, and tech support's weak answer to my question just drops my rating. It also makes me wonder how those new VG Strats play if i'm using the 'same' thing...

Feature:
The only thing I would change is to have the display show the name of the voice you're using. Other than that, it's a great basic unit.

Quality:
Reliability for regular use seems good. I just play a couple weeks a month in church, but I have a friend who uses one of these every night playing in bars, etc.

Value:
I guess it's worth the money. It's certainly less than a comparable keyboard module.

Desirability:
People will stare with open mouths when you play this thing. They can't figure out how you're doing it.

Sound:
The sounds are impressive. Many are not practical for live use, but all synths are like that. The weakest are the acoustic guitar sounds. But brass, woodwinds, strings, vocal chorus...I love it.

Ease of Use:
It couldn't be easier. It takes maybe a half hour to figure it all out, and from then on it's just a matter of practicing like anything else.

Support:
Don't know...never needed to contact them yet.

Overall:
I got into this for the long haul. This unit should last for years.

Feature:
The unit came with all accessories, as advertised. Setting up is not explained properly in the ads which you'd read before buying. The pickup unit itself is a bit too high for a stratocaster, so I had to raise the strings a bit on the bridge. That resulted in a tremolo bridge issue, as the new height ofthe strings, no matter how slight, pulled the bridge forward because of the increased "moment" (in mathematical terms, that would be the product of force and radius).

Quality:
No doubt quality control is great, but sometimes the best engineers can design a great product but fail to see the "practical" problems, as with the control knob I mentioned above.

Value:
Not worth the trouble if you can play keyboards. I should have bought a Juno synth instead. In Australia, this guitar synth caost me $979 (AUD).

Desirability:
The synth unit looks beautiful. The guitar component also looks good but fails in practical aspects.

Sound:
The sound is reasonably good - some excellent and others not so good. Sometimes, response leaves a lot to be desired. The first string has a low strength problem, no matter how much I adjust the space between string and picku.

Ease of Use:
Easy to get different sounds. One major problem is the twsit control on the guitar controller. As you play, your arm runs against the control and turns it to low. It is annoying that the volume then goes down right in the middle pf playing, so instead of concentrating on your playing you have to be mindful of the control knob. This is in fact the biggest flaw in the design of this gadget! and that would be the singularly main reason why I should not have bought this thing.

Support:
Have not had to call support.

Overall:
If I could sell it now and recoup my money, I would. Unfortunately why would anyone buy it from me for the same price as a new one?

Feature:
The divided pickup came included and this was my biggest fear before buying. I have a number of guitars and had not decided which to attach the pickup to (you have to fix the pickup to your guitar, then cable it to the synth, then off to your amp/recording device). Attaching the pickup proved quite problematic despite having read quite a bit beforehand - you have 3 basic choices 1) double sided tape 2) drill holes in your guitar body and attach by screws 3) use a plate that is provided that sits under the bridge. The plate holes did not line up with any of the bridge holes on any instruments I wanted to use, so it was the sticky tape route for me. It sat easily and surprisingly firmly next to the bridge on an old Telecaster, but even after a day of fiddling I could not get the arc of the strings to line up with the curve of the synth's pickup. There is a way of adjusting the way the synth's pickups are orientated by no matter how I jacked up one end of the pickup, varied string height (thus changing the action) or altered the pickups by turning the screw in the middle - I could not get the settings balanced. If you buy one you will learn how to set the signal strength via the unit itself, but this proved ineffective also. So I removed the pickup and put it onto a Fernandes Vertigo X and despite the manual stating that the strings should be 1mm from the pickup (there is a tool that measures this that is included) - things worked instantly with equal signal strengths from all strings with no adjustments. I found the supplied tape and spacers useful and they did the job well enough. As the pickup itself takes no physical punishment it should not come off - but time will tell. The pickup attachs to the control unit via a variable length cable and sits snugly on the guitar via the strap connector and an additional bracket with no apparent long term harmful effects or damage.

Quality:
I expect the unit to last around 3 years, it came unblemished. My biggest concern is the cable plug that goes into the guitar - doesn't seem that durable. No backup.

Value:
It is not worth the money as most of the sounds are just fillers.

Desirability:
No doubt it is very clever and given the size, 'fun', but certainly not sexy. It is too difficult to use to produce 'clean' sounds for the average user, the tracking is woefully slow for anything approaching a fast piece of music.

Sound:
My first impressions of this were good, but as time has gone on, what I thought was a very useful range of sounds has been weathered down into perhaps just 10 - 15. I bought it solely to record with at home and have found that the majority of the sounds have too may inherent flaws and problems when playing to be included in my review. I would say that it is not practical to play live. I used it with a Boss GT6 and the output was mush - you will have to adjust your playing style to accomodate the various nuances of using a string based synth.

Support:
No problems as yet with this, but I have had dealings in the past and it wasn't a nice experience as they are simply too many people out here with things that need dealing with and not enough people dealing with them.

Overall:
I would not buy another and use it increasingly less. It does not meet my musical requirements. When I bought it I choked a bit as I have a 12 string electric guitar and an electric sitar and thought I would be selling them as the GR-20 emulates both - I needn't have worried.

Feature:
This is a stand alone synth. I can hook up a keyboard controler and play it that way, or midi to the computer to run a soft synth. It comes with everything you need except a guitar cord.

Quality:
The GR-20 is made well, as all Roland products. (no I don't work for Roland)

Value:
Well worth the money.

Desirability:
I Love it. I sequence it with my D-8 and it adds tons of rich texture to many of my tunes that without it would be boring.

Sound:
The sounds are amazing. Why would anyone complain about too many sounds? I can tweak them any way I want. Ghost notes can be fixed by playing closer to the bridge, or by adjusting the sensitivity level. You've got to experiment a little.

Support:
Have'nt had to deal with them.

Overall:
I'ts not perfect, but it's only $600. You can't buy a decent synth for that price, let alone one that you can play with a guitar (remeber in the 80's these things were 2K and not as good). I would recomend this to any guitar player who writes and arranges, but doesn't have musicians at hand.

Feature:
Too many sounds... they could keep a bunch of the percussion etc... Digital out would have been nice (or even balanced). More midi control would be a plus... but this has the basics.

Quality:
Plastic case... not too heavy duty. The tracking is finnicky, but that's the nature of the technology. You must play accurately and playing in the higher registers produces better tracking (you can always transpose if needed).

Value:
For the price point, it's very reasonable.

Sound:
This has some surprisingly good sounds in it. I bought it to control my Kurzweil, but was pleasantly surprised to find some good pads, vocals, organs, and a number of wind instruments.

Support:
Never used.

Everything you could want, I can"t say enough about the ease of useing this unit.Plug in,turn on, be amazed!!!

Quality:
Very well made,nice looking piece of equipment.This unit is very tuff and would offer many years of servics. No complaints.

Value:
Well worth the money.

Desirability:
Nice looking sleek and black. Just a nice addition to my setup.

Sound:
Rich sounds.Close your eyes and you"d never know the diff. The GK-3 tracks true. The keyboard sounds are as close as you can get next to buying one.It would work very well in any style of music. The unit sounds good by it self but with a pre-amp it realy warms up nice. As true a sound you can get without going bankrupt buying the whole band.

Support:
Never had to call.

Overall:
There is no way I will use all the sounds this thing makes. The sounds are so life like you won"t beleive your ears.If I we"re to lose this piece I would have to buy another.
