Seymour Duncan SMB-4A

The Alnico magnets, together with unique coil windings, have the effect of extending both ends of the frequency spectrum beyond that of the ceramic magnet version. In other words, the Alnico version is both warmer on the bottom and more detailed on top. Comes with four-conductor hookup cable and logo cover. Generally used together with STC-3M3 and -3M4 Tone Circuits for optimal tonal control. Replacement for 4-string Music Man® StingRay® basses from 1976 to present and for 5-string Music Man StingRay basses up to 1992.
