This Seymour Duncan Vintage Staggered for Stratocaster pickup uses hand ground alnico 5 rod magnets and heavy Formvar magnet wire with a special wind pattern to produce that bright, glassy, bell tone with all of the bounce and sparkle youd expect from the best 50s Strat pickups. The treble attack is crisp and immediate, while the low end remains articulate and focused. Chords ring out with clear note to note separation.
