The Rickenbacker 4003 is a legendary, neck-through-body bass famous for its ringing sustain, piano-like clarity, and driving mid-range. It features an all-maple body and neck, a 33 1/4" scale length, and dual single-coil pickups. [1, 2, 3, 4, 5]Key features and recent structural updates include:

• Tonal Versatility: Includes a 3-way pickup selector, individual volume and tone controls, and stereo ("Rick-O-Sound") outputs. The treble tone knob features a push-pull switch that engages the "Vintage Tone Circuit," emphasizing classic '60s treble bite. [1, 2, 3, 4, 5]
• Modern Hardware: The latest versions feature the fully adjustable RIC v2 bridge for precise string spacing and action, along with Schaller Deluxe tuners. [1, 2, 3, 4, 5]
• Neck and Truss Adjustments: Recent production models have moved to a more playable, thinner neck profile reminiscent of the vintage 4001, and now feature a single-action truss rod system that makes neck relief adjustments significantly easier than older dual-rod designs.
  
  
  This bass comes from the estate of Alabama musician Willie Doss, who assembled a professional collection over four decades of performing, recording, and teaching music.
