The EMG-81 is a famous active humbucker guitar pickup manufactured by EMG. It is usually considered a lead pickup for use in bridge position, paired with EMG-85 as a rhythm pickup in neck position (Zakk Wylde is famous for this configuration).
It's not uncommon, however, to see a guitar with two EMG-81's in both bridge and neck positions (for instance, Kirk Hammett's EMG-KH21 pickup sets, which include 2 EMG-81 pickups for both neck and bridge positions).The EMG-KH20 has an EMG-81 in the bridge and 2 EMG-S single coil pickups in the middle and neck positions.
The EMG-81 pickup is preferred as a lead pickup because of its high output, and smooth control from having a rail magnet. Rail magnets tend to sound smoother through guitar bends because they have a constant "rail" that runs through the pickup, while typical ceramic magnets have poles at each string that lose signal strength as the string bends away from the ceramic pole.
