This is the 7 string version of the SH-5 pickup. The pickup itself is otherwise the same as the 6 string version. String spacing for this pickup is 2.42" (about 2 13/32", 61.2mm). The Seymour Duncan SH-5 has been described as having "P.A.F. on steroids" tone. The SH-5 is great for classic rock, heavy rock, funk, punk, R&B, metal and drop-tunings. The SH-5 offers beefed up Patent Applied For (P.A.F.) tone for a hard-driving, kickin' sound with the right balance of power, sustain, and distortion. This pickup cuts through with a distinctive high end and midrange attack. The ceramic magnet and custom coil design give the SH-5 compressed dynamics, an enhanced harmonic structure, and a punchy bass. Perfect for dropped tunings without "mushing" out. Comes with four-conductor hookup cable. Recommended for bridge position. Often a Duncan Custom is paired with an SH-1 '59 in the neck for bigger P.A.F. tones in the bridge and vintage-correct P.A.F. tones in the neck. Designed for balanced and warm instruments. Works especially well with rosewood fingerboards. This pickup is used by Mike Chlasciak / Halford (bridge), Whitey Kirst / Iggy Pop (bridge), Rick Jackett / finger eleven (bridge), Will Adler & Mark Morton / Lamb of God (bridge).
