The Jackson JS3V Concert Bass features an Indian cedro body, bolt-on maple neck with Indian rosewood fingerboard, 24 jumbo frets, 34" scale, Jackson dual humbucking high output pickups, a high-mass bridge, and black hardware. The Jackson JS Series is the affordable axe equivalent. Built with 30 years worth of Jackson expertise, each JS is swift, sleek and deadly. Compound Radius Neck The neck is the most important part of any bass. The Jackson JS2 has a compound radius neck that begins with a smaller radius at the nut that gradually becomes larger as you play up towards the bridge. Guitarists and bassists alike appreciate a compound radius neck for the comfort and speed in fingering it allows. Case sold separately.
