The SBT (Soundboard Transducer) Series pickups reproduce a full, natural, transparent tone, and can be mounted on any type of acoustic stringed instrument equipped with a flat soundboard. The Model SBT-C is recommended for easy installation on nylon string guitars, steel string guitars, dulcimers, and similar stringed instruments. Fishman’s SBT pickups sense the microvibrations of a soundboard, and are a practical alternative to more expensive bridge mounted units. When paired with an impedance-matching preamp, such as our Platinum Stage, Platinum Pro EQ or Powerjack, the full potential of the SBT-C can be realized.
