This popular transducer is designed for installation at the bottom of a 3/32" (2.38mm) wide bridge saddle (saddle not included).
Martin installed this model for several years on their amplified 6-string guitars. This pickup is designed for string spreads up to 2-1/8" (53.97mm).
Includes the Fishman Switchjack: a stereo jack that can be used for mono, stereo, or mono with battery switching capabilities. Like all passive transducers, this pickup does not require a battery. The Switchjack™ tightens from outside the guitar, and accepts a standard 1/4" (6.35mm) plug. 1/2" (12.70mm) diameter mounting hole required. An impedance-matching preamp is recommended, but not required.
