Canuck:
Roland sells the GK-2A in two configurations. One is an add-on, to be slapped onto a guitar: that's the one you see most often on eBay. The other is a kit of parts that you can wire into a new guitar. I found the latter at a local guitar store. They'd had it in stock so long that they sold it to me for $150, rather than the $225 list price they normally sell it for. You have to be comfortable with electronics to go this route, but it worked out fine.
Jehle:
Yeah, the lack of regular pickups results in a very mimalist, clean design, that shows the most possible wood. That was the idea.
Brian:
Yeah, that was the whole idea: pretty AND a nice guitar!

Thanks for turning me onto this site! The guitar sounds just like any other Roland VG-88 guitar: nothing especially different than any other.
James:
The two black dots are the pushbuttons that come with the Roland kit. They're momentary contact buttons, that allow you to tell the VG-88 to go Up or Down by one stored voice. The only problem with them is that they are VERY easy to push, and sometimes when I end a run with a flourish, I accidentally hit one of them. Next time, I'll use a momentary contact toggle, and put it further down on the body. So far, this is the only problem I've had with the guitar. As explained above, Roland sells a kit of parts for installation in custom guitars. It sells for the same as the add-on pickup, but is much more difficult to find on eBay at a reasonable price. There are plans out on the net for taking the add-on pickup, disassembling it, and using it like this, but I didn't take that approach.
