- The Rickenbacker 4003 Bass is famous for its ringing sustain, treble punch, and solid underlying bottom end. It's also famous for its distinctive, elegantly curved body shape, accentuated by a subtle strip of binding, deluxe triangular fretboard inlays, stereo output, neck-thru-body construction, double truss rods, and high output single-coil pickups with wide response range and brilliant clarity. The Vintage Tone Selector activates a capacitor in the treble pickup circuit to emphasize the high end. Pressed in, you get the familiar 4003 sound, pull it out to add bite and crispness. Comes with a deluxe hard shell Rickenbacker case.
