The Gibson Patent Applied For humbucker pickups from the 1950s are considered by many musicians to be the “holy grail” of vintage electric guitar pickups. Among them, the unique set that was installed in the legendary “Greeny” Les Paul are some of the most famous. The new Greenybucker set is instantly recognizable from a sonic perspective; their distinctive sound is partially from the out-of-phase middle switch position due to the neck pickup’s reverse magnetic polarity. The Greenybucker pickup set was developed with input from Greeny’s current owner, Kirk Hammett, and with specifications taken from the actual Patent Applied For humbucker pickups on that world-renowned guitar, including asymmetrical coil windings and unpolished Alnico 2 magnets.
