Piezo Pickups in Solid Brass Bridge The piezo pickups used on the TRB models use individual bimorphous piezo elements for each string, all built into a specially designed bridge which is machined from solid brass. Figured Maple Body with Thru-neck Construction The TRB-series basses feature figured maple bodies that offer the requisite tone as well as outstanding visual appeal. Neck-thru Models Because piezo pickups directly pick up the resonance of the instrument body, the body itself must be made from the finest woods and designed to deliver rich, deep tone. The neck-thru design of theses basses affords the best possible foundation for this amazing sound.
