Jackson celebrates the anniversary of Megadeth’s landmark album, Rust in Peace, with the Jackson X Series Signature David Ellefson 30th Anniversary Concert Bass CBX IV. It’s Ellefson’s intricate bass skills and unparalleled playing style that cemented the record as one of the finest thrash metal albums of all time. Bearing Ellefson’s personal touches, this monster bass is packed with enormous Jackson sound and the hyper-fast playability required by the fleet-fingered musician.

This signature David Ellefson Jackson bass features a poplar body with ergonomic contours that provide the perfect platform for launching a musical assault—the upper contour provides a comfortably stable anchor for pick or fingerstyle playing while the lower contour provides perfect balance when propped on a knee for monitor stands. The through-body quartersawn maple neck features a scarf joint and graphite-reinforcement rods that protect against extreme environmental and climate changes. Built for highly technical lightspeed playing, the 12"-16" compound radius laurel fingerboard flattens out as you move up the neck for increased playing comfort and speedy articulation.

Earth-shaking EMG P and EMG J pickups in the neck and bridge provide plenty of girth and cut. Dial in your thunderous bass tone with a 3-way toggle switch, single volume control and two-band EQ for boosting treble and bass. The Jackson HiMass 4-string bridge sharpens your notes’ attack for extra punch and clarity, granting enhanced sustain without significantly altering the bass’ fundamental tone.

A force to be reckoned with, the Jackson X Series Signature David Ellefson 30th Anniversary Concert Bass CBX IV displays Jackson’s distinctive style with an eye-catching Quicksilver finish, all-black hardware—including everything from the bridge to the Jackson sealed die-cast tuning machines, pearloid sharkfin neck inlays and Jackson’s signature pointed 4-in-line black headstock. The headstock also features the white "Radiation" logo, and Ellefson’s signature is embossed on the truss rod cover.
