Designed in conjunction with one of the founding fathers of thrash metal - highly acclaimed bassist David Ellefson of Megadeth - the X Series Signature David Ellefson Concert™ Bass CBX IV is a beast of a bass. Bearing his personal touches, packed with enormous Jackson sound and the hyper-fast playability required by the fleet-fingered bassist, this instrument is a force to be reckoned with.

Redesigned ergonomic contours provide the perfect platform for launching a musical assault - the upper contour provides a comfortably stable anchor for pick or fingerstyle playing alike while the lower contour provides perfect balance when propped on a knee for monitor stands. 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.

An earth-shaking pair of EMG® HZ35 active humbucking pickups in the neck and bridge positions provide plenty of girth and cut as an active 3-band EQ bolsters their native power, shaping and refining it for maximum impact and versatility. The blend knob allows you to mix the pickups to your taste - add more of the neck pickup for a touch of warmth, or bring up the bridge pickup for more cut. 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.

This bass proudly displays Jackson's distinctive style; all-black hardware, including everything from the bridge to the Jackson die-cast sealed tuning machines, durable gloss finish, pearloid sharkfin neck inlays, single ply white neck binding and Jackson's signature pointed 4-in-line headstock along with a white "Radiation" logo and Ellefson's signature embossed on the truss rod cover. Only one instrument is hardcore enough to keep pace with Ellefson's technically demanding requirements - the Jackson David Ellefson CBX IV - and now it can be yours.
