On the shop floor of the original Gibson plant in Kalamazoo, Michigan, the earliest Gibson "Patent Applied For" humbuckers were wound using imprecise machines, resulting in pickups with varying degrees of output and tone. The BurstBucker line of pickups represents Gibson's drive to recapture the magic of the original "Patent Applied For" humbuckers. First introduced in the early 1990s, the Gibson BurstBucker - Types 1, 2, and 3 - successfully captured the subtle variations of true, classic humbucker tone with historically "unmatched" bobbin windings and Alnico II magnets. They produce an airy, full tone, and when overdriven they achieve a magical distortion with the slightly enhanced highs that made the originals famous. BurstBucker Type 1 features a lower output, excellent for the neck position. None of the BurstBuckers are wax potted, and all feature vintage braided two-conductor wiring. Color: Double Black. Specs: Output: 8,4 - Position: Both - Magnet: Alnico II - Wiring: 2-Conductor.
