The Jackson JS2 Kelly Bird basses are truly fabulous creatures with formidable looks based on Jackson's classic Kelly body style and thunderous bass tone and performance. The Kelly Bird JS2 four-string bass features a 34" scale, an offset mahogany body, one-piece bolt-on maple neck with satin back finish, graphite reinforcement and scarf joint and a 12"-16" compound radius Amaranth fingerboard with 21 jumbo frets and pearloid block inlays. Jackson dual high-output bass pickups provide an earthshaking sound, with a Jackson high mass bridge for solid stability, improved sustain and warmer tone. Includes two volume knobs and a master tone control.
