The Realist Cello acoustic transducer was designed by Ned Steinberger in association with David Gage. A primary design goal was to create a transducer that would work equally well for pizzicato and arco through commonly used amplifiers, without requiring a pre-amp or other active, battery powered gear. A flexible element fits under the bridge foot so that it picks up sound from both the bridge and top plate. Produces a rich and powerful response that is acoustically true for both pizz and arco without adjusting controls. No preamp necessary. Easy installation. Just plug it in. Cable is not included. The Planet Waves Classic Series 20' Instrument Cable or the Fishman 15' Stereo Cable works perfectly with this pickup.
