Gibson Burstbucker #1 Alnico II Humbucker, Nickel Cover. BurstBucker™ pickups from Gibson Gear now give guitarists a choice of three replica sounds from Gibson's original "Patent Applied For" pickups - the pickups that give the '59 Les Paul Standard its legendary sound. The three BurstBuckers™ - all with unpolished Alnico II magnets and non-potted coils, like the originals - represent the variations found among vintage Gibson humbuckers. Burstbucker™ #1 pickups are slightly underwound, with medium "vintage" output, and work well in both bridge and neck positions.
