    I found this pinout on another site for the output off the pickup:
    DIN-13 PINOUT - guitar
    1 = string 1
    2 = string 2
    3 = string 3
    4 = string 4
    5 = string 5
    6 = string 6
    7 = mono guitar signal
    8 = synth volume (0-5VDC)
    9 = n.c.
    10 = SW 1
    11 = SW 2
    12 = +7VDC
    13 = -7VDC
    Shell = Gnd

    I have built my own 13 pin din cable with all the connections I think I need, I am supplying 7v and -7v pins 12 and 13 respectively, ground to the shell, and I have tried supplying 4v on pin 8 as well as leaving it open. I have an oscilloscope connected to pin 1 and ground as I test one string to try to get a signal, but I dont get any results. The power indicator light isnt on either, Im not sure if it needs something more to power it than just the +-7V.

    Anyone know anything that I dont about these pickups?
