"hypothetically speaking" Using an active on-board preamp, a stacked blend pot has a wire leading from the preamp to the pot, just as in this pic: the red + wire leads from the preamp to the pot. As the pot is swept back & forth singling out one pickup, this would in essence send 100% of that pickup signal to this red + wire? is this correct? Using an ohm meter, I verified that if I singled out pickup #1, I would get continuity between that center connection for pickup #1 to the red + connection. Center pickup connection for #2 would yield continuity to ground, sending P/U #2's signal to ground. Sweeping the pot in the other direction did the same for pickup #2. If I were to use a preamp that originally had a blend pot in it for use with 2 pickups, in a bass that has only one pickup (ie. a Stingray) would I wire the hot + wire from the pickup to this preamp wire that originally went to that lower right hand corner of the blend pot as in the pic (basically eliminate the blend pot)? EDIT: I powered the preamp with the 9v battery and verified that this wire in question coming from the preamp to the blend pot does not have power.
