Seymour Duncan California 50s Vintage Staggered SSL-1 Strat SetMaker: Seymour Duncan Model: Vintage Staggered SSL 1 Condition: New Description: Our Vintage Staggered for Stratocaster pickups (SSL 1) use hand ground alnico 5 rod magnets and heavy Formvar mag wire with a special wind pattern to produce that bright, glassy, bell tone with all of the bounce and sparkle you would expect from the best Strat pickups from the 50s. The treble attack is crisp and immediate, while the low end remains articulate and focused.
