I am fitting a set of active/passive Select electronics from a beat up Hohner B2A bass. Does anyone have anything resembling a wiring diagram for these? The set consists of 2 pickups (in a humbucker-style casings), 3 pots (2 vol one tone), battery compartment with a preamp, a 2 way switch(active/passive) and a led. Any help appreciated!
i'm pretty sure the selects themselves are passive; they just have the one white coax lead, right? that's a center hot surrounded by a braided ground. wire them up like you would the two leads from any other passive jazz pickup. is there a separate little circuitcard thingy with the red wire to the battery clip attached to it? it should have a little plastic trimpot that's the overall gain control, as well as connections to the bass/treble knob stack and a mini-toggle for active/passive switching.
