The Jazz Bass (or J Bass) is the second model of electric bass created by Leo Fender. The bass is distinct from the Precision Bass in that its tone is brighter and richer in the midrange and treble with less emphasis on the fundamental harmonic. Because of this, many bass players who want to be more "forward" in the mix (including smaller bands such as power trios) prefer the Jazz Bass. The sound of the Fender Jazz Bass has been fundamental in the development of signature sounds in certain musical genres, such as funk, disco, reggae, blues, progressive rock, heavy metal and jazz fusion.
