I should clarify that my initial post was a bit of a simplification. I am actually using this with a 10 string pedal steel guitar, which has a narrower 8mm string spacing. The GK-3B is adjustable down to 16mm spacing, so I can cover the strings by staggering two of them (strings 1,3,5… and strings 2,4,6…). I would be happy to use a different pickup that is better suited for this if one exists.
My plan was to buy the GK-3B kit which has a pickup with a raw molex connector (6 hot signals, ground and shield). I would then take the wires out of the molex and merge them into a single 10 wide molex:
Note that I dropped one hot signal from each pickup (each one covers 5 strings) and I have merged 3 of the hot signals into a single wire so I can get it down to 8 (H9000 only takes 8 analog in). I would then buy 10 wires and a DB25 male connector and make my own DB25 cable which routes these signals to the correct pins.
I wasn’t planning on supplying power since I’m not using the actual GK-3 processing unit, just the pickups. I was hoping that a very quiet signal would be fine since I can just apply a lot of gain via -10db + THRU algorithm 24db in/out gain + gain in MIDI Guitar software. I imagine the signal will be very noisy but so long as it can detect the pitch of the notes that should be fine.
