Need wiring diagram for Aguilar OBP-1

    I've recently acquired an Aguilar OBP-1 onboard preamp
    to compliment my two EMG-HB pickups on a
    1969 Guild Starfire II bass. The normal wiring diagrams
    they give does not include a pickup selector or Master Volume.

    As set up right now (EMG-BTS) there is a Pickup selector switch,
    Master Volume, Neck pickup volume, bridge pickup volume,
    and separate bass and treble controls. I would like to duplicate
    this if possible.

    Luckily (thanks Ron Wickersham) the bass was modified in
    1975 with Alembic pickups and an 18V preamp, so there is
    space for two 9V batteries already.

    I know Edwin took the wise approach when he modified his
    Guild with Barts/active preamp by cutting an access plate
    on the back of the hollow body, I'm still insane and route
    the electronics through the F-holes <sheepish grin>

    Thanks in advance for any help, advice, consolation
