Each SSL-1 pickup is a vintage-correct reproduction of an original Strat pickup, using hand ground, sand cast, Alnico-5 magnets arranged in a vintage, right-handed, stagger pattern; hand-fabricated, lacquered, forbon bobbins; heavy Formvar magnet wire; and waxed cloth hookup cable. The materials and construction are as vintage correct as the sound: that sweet, familiar, bell tone with high-end bite and "quack" in the notch positions. Plus, you get hum-cancelling in positions "2" and "4" due to the reverse wound, reverse polarity middle pickup. Great for blues, classic rock, and country.
The bridge model is designed for bridges with traditional string spacing of 1.925" or 48.9mm measured over the bridge pickup.
