The first commercial unit of the Precision Bass was produced in October 1951. It had a “slab” (non-contoured) ash body with two “horns” (as opposed to the Telecaster’s one; this provided greater balance and was subsequently adapted for the Stratocaster), a one-piece 20-fret maple neck fixed to the body by four screws (despite use of the technically incorrect term “bolt-on”), a single pickup, black pickguard, Kluson tuners, treble-side thumb rest, a string-through-body bridge with a cover (with a mute), and two pressed fiber bridge saddles. It borrowed several features from the Telecaster, including its headstock shape, neck plate, truss rod nut, potentiometers, two domed chrome control knobs, output jack ferrule and strap buttons. One of the most important features of the Precision Bass was its scale length, which Leo Fender, after careful consideration and lengthy experimentation, set at 34”. It was available only in a blonde finish.
