Burstbucker ProTM Pure Sweet Tone The BurstBucker ProTM enhances the vintage edge of Gibson"s popular BurstBuckerTM pickups with the added feature of an Alnico 5 magnet. In 2000, Gibson"s new BurstBuckersTM captured the subtle variations in true humbucker tone with historically accurate unmatched bobbin windings and an Alnico II magnet. Two years later, in keeping with Gibson"s long history of experimentation and innovation in pickup design, Gibson developed an Alnico 5 BurstBuckerTM specifically for new Les Paul Standards. The outstanding performance of this new pickup (originally called the BurstBucker V) led to an overwhelming demand for an after-market version. With the BurstBucker ProTM, all Pure Tone Lovers can now have stunning humbucking tone.
