The seller doesn't know what he's talking about. ALL Alembic pickups are low impedance. If you hook them up to the typical passive electronics found in most instruments, there will be very little output. Alembic pickups require a pre-amp, as do all active pickups. Some. like EMGs, have the pre-amp built into the pickup casing. Others, like Alembic, wire the pickups to a preamp in the control cavity. Buy these, drop them into a stock Fender, and you're going to be extremely disappointed.
