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.

EMG 35HZB/EMG 35HZN Pickups (Active Three-Band EQ)
The EMG 35HZ is a modern passive bass pickup featuring a dual-coil humbucking design for low noise and plenty of output. Its ceramic magnets produce very pronounced and focused mids, as well as a fast and quick bass response. The strength of the magnets allows the pickup to retain articulation and clarity, even when introduced to extreme gain, which makes for a great choice for fast-paced metal. An active three-band EQ provides separate active controls for bass, mids and treble.
