Hi Todd, your brown basses will come with a stereo jack and the signature basses come with a mono output jack. You can, as i did, order a wiring loom from alembic to convert the signature electronics to anniversary electronics. Then you can have separate pickup outputs.Then you can either drill two holes to mount the pickup selector switch and mono/stereo switch or insulate them and leave them both inside the cavity switched to whichever options you prefer. That is how my conversion is at the moment until i feel brave enough to drill the bass.
