Need schematics for passive/active switch

[hack]

Hi,
I would like to add a passive/active toggle to Audere JZ3 preamp (volume, Z switch, Mid/balance stack, treble/bass stack). Can anyone give me a short guide as to how to wire the above switch? Schematics woud be appreciated.
The bass is a 75RI jazz with Nordstrand pickups. (Can't go wrong with this setup IMHO).
Thanks.

Contact audere - Dave can probably just email you a diagram (not a schematic - which you probably don't want anyway). Or you can just google or go to whatever site (Aguilar OBP-3 for one) that has a passive option then cut/paste it into the Audere wiring - assuming you know the Audere wiring.
