A Realist Acoustic Transducer for Violin with a 1/4" jack. Designed by Ned Steinberger in collaboration with David Gage. 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. Please note: This is an older version, not the current Copperhead model. This pickup has been taken out of the packaging at some point, but is in near new condition.
