No, that's not right. The gk-2 does indeed have six discrete analog outputs, one for each string. There is no multiplexing. I believe there is also a line with all the signals mixed. It also contains a small on-board preamp, for driving the lines. You need to supply the pickup with +/- 8V to power the preamp. The gk-2 works fine for hex guitar applications, which is why we were making the infinity compatible with it at g-wiz. Making a gk-2 breakout box should be pretty easy. Same with RMC and other hex pickups. I might have the pinout for the gk-2 somewhere, I'll look. Also, if you have an acoustic guitar with bridge piezos, you might want to take a peak inside. Many of those are also hex, and just get mixed for the output. Oh, as far as Charlie Hunter, He just has two separate pickups. One for the bass strings, one for the guitar. Each goes to it's own output. kim ______________________________________________________________________ Kim Flint | Looper's Delight kflint@annihilist.com | http://www.annihilist.com/loop/loop.html http://www.annihilist.com/ | Loopers-Delight-request@annihilist.com
