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 81s 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.

EMG 81 can be recognized by a humbucker form-factor and silver embossed EMG logo.

History and design

EMG-81 was developed in 1979 along with the EMG 85, and, since 1981, it is the model that made EMG famous. Construction is similar to traditional U-shaped pickups, but there are no separate pole pieces; steel bars (rails) are used instead. Alnico magnets have been replaced with more powerful ceramic ones. While nominal output is the same as EMG 85, lower noise ratio gives more gain opportunity. Therefore, EMG 81 is loudest of all EMG pickups.

As most other modern EMG pickups, EMG 81 has 3-wire "quik-connect" output, that comes as a 3-pin male connector on a pickup body and a 3-wire cable to connect it. Easy wire color code scheme that is the same for all EMG products simplifies soldering and installation.

18v Mod

Some guitarists increase the power source from 9v to 18v by adding another 9v battery wired up in series. Many players believe this creates more clarity, articulation and headroom. The pickup is rated at 27v so the mod is harmless and there are even some guitarists, albeit very few, that perform 27v mods although the improvement is questionable over the 18v mod.
