Feature:
It comes with a bracket to aid attachment to Les Paul guitars. I used this and it works extremely well. I have it running throught a Roland GI-20 into my sequencer and it works perfectly. I am hugely relieved to have a great MIDI interface that is not a keyboard.efore buying the GK-3 I read a lot of user reviews, so I was anticipating a bit of a struggle to fit it to the guitar effectively. In reality, I followed the instructions in the manual and made slight adjustments to the pickup height using the included mounting materials and it all worked great.

Quality:
It appears to be very well made and works flawlessly. I am very impressed. I am puzzled that so many people have had trouble with it (bad tracking) this is absolutely NOT my experience. It tracks like glue when fitted to a Les Paul. I made sure that the senstivity was optimised for each individual string before really playing with it. The adjuster mechanism is very effective for letting you squeeze out the optimum performance. I will re-otimize the pickup setting at some point in the future but for the time being it is already pretty much spot on. It was not that difficult.

Value:
I had been playing Godin/Brian Moore guitars for a comparison and I think I have to say that the RMC pickups and the GK-3 have very similar performance. I really was not expecting the GK-3 to be as good as it it (it was a temporary measure will I save for the Godin). I have been doing fast bluegrass flating picking stuff and it tracks it perfectly using a Banjo patch. I have recorded the midi data into my sequencer and it is literally perfect even over runs of minutes. Considering that the alternative guitars cost a LOT of money this pickup is fantastic value.

Desirability:
I have been test running it for a few days and I can already say I would buy another. It solves a lot of problems.

Sound:
Its a midi pickup therefore no sound on its own

Support:
I have not had the need.

Overall:
I don't have the time to really learn keyboards. It is sooooooooooooo worth the money. I am now laying down bass lines and banjo stuff like a madman. FREEDOM!!!!!!!!

Feature:
It has a lot of mounting material. For my Gibson installation I use the supplied mounting bracket. It's advertised as having a retractable cable, that's a bloody lie. Retractable is like a vacumm cleaner cord which this is not. All it has is a place to coil the cable around.

Quality:
It's made of plastic. It sticks up so how can you use your hard case with it? All this is is a cheap product that stupid people buy hopeing to get into midi guitar and it's just a joke. Maybe 15 years ago this garbage was all there was but the Brian Moore and Godin models are the only real choice. Anything with a magnetic hexaphonic pickup is only suitable for triggering pad sounds. It won't work with quick funky bass lines and there is absolutely no way in your wildest dreams that you could use this for notation of a score.

Value:
Um well, it's actually quite a bit of money for a chunk of plastic but it is cheaper than a whole new guitar... What does that mean in terms of value? I dunno but since it doesn't work properly no matter how it's adjusted it's extrememly bad value because it's virtually useless. It's like a Behringer effect pedal in build quality and feel, and also performance. It's the bottom of the barrel. If you had nothing else this POS will be all you can use to drive you insane. MUCH MUCH MUCH better off with a midi keyboard for the price of this pickup! Plus it's not just the pickup, there's whatever you want to plug into. So in that case you should be prepared to drop some cash into a setup that actually works for one thing...sheesh!

Sound:
This product is garbage. I can't imagine how bad things must have been with older products like the GR-50 but the GI-20 is reputed to be the best tracking device going. The GK-3 isn't very good at cleanly picked fast bass note detection. Don't believe anything you read about this being anything like worth buying.

Ease of Use:
It has instuctions. You set it up according to the instructions. It comes with a measuring gauge you can put between the pickup and string to get the "correct" height. Then you adjust the individual string sensitivities on your GK device. For me it is a Roland GI-20 which is the best tracking device made.

Overall:
How long do you expect to be satisfied with this product before searching for another product? That's a classic question. Since this pickup is a total joke I returned it to the supplier and have ordered a Godin Freeway SA. If that sucks that can go to and I will just use my keyboard to access soft synth sounds. I doubt that it will be anywhere near as hopeless as the GK-3 though. If you can play an octave pedal then that should be how you need to play like to get the synth to trigger properly. You set it up exactly at the right height, and with the right sensitivty per string and then... it can't track anything but quarter notes with any success. You can adjust it closer than 1mm, or further, and adjust the play feel, the sensitivity and how you play but as soon as you want to play something a little funky on the bass strings it's missing notes.
