The Seymour Duncan SDBR-1 Duckbucker Strat Bridge Pickup is a vintage output single-coil-sized humbucker. Excellent for country, pop, surf, rockabilly, blues, ska and classic rock. Using a design and a voicing based on Vintage Rails™, Duckbuckers incorporate six fully adjustable pole pieces together with a unique, split blade design. You get all the warm tone, cool output, and outrageous "quack" of a vintage Strat® pickup, but no hum. Though tonally similar to Vintage Rails, the mini pole piece design behaves more like a traditional pickup when string-bending. Comes with four-conductor cable. USA Patent No. 5,525,750. Available for both bridge and neck/middle positions; and in an incredibly versatile set with an SJBJ-1b JB Jr. in the bridge, an SDBR-1n Duckbuckers in the middle and an SL59-1n Little "59 in the neck. For all well-balanced instruments. Works equally well with maple and rosewood fingerboards. Wire in parallel for Vintage Strat tones, or in series for higher output. Players include Jennifer Batten / Jeff Beck Band, Chuck Garvey / moe., Mike Scott / Prince, Joy Basu / Jessica Simpson, Nick Lashley / Alanis Morissette and Mick Jagger, Lou Toomey / Brooks and Dunn Specifications DC Resistance: 2.6k (neck/middle), 3.0k (bridge) Resonant Peak: 7.2 KHz (neck/middle), 6.8 KHz (bridge) Magnet: Ceramic bar Overall dimensions: 3.31" L x 0.73" W x 0.80" H (2.58" W at top of casing) Pole spacing: 0.41" typical Screw hole spacing: 3.03" to centers
