34:T7ad,

Designed in conjunction with one of the founding fathers of thrash metal - highly acclaimed bassist David Ellefson of Megadeth - the 4-string USA SIgnature David Ellefson Concert™ Bass CB 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. 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 titanic EMG® 35CS active neck pickup and 35DS active bridge pickup 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.

Designed for highly technical lightspeed playing, the 12"-16" compound radius rosewood fingerboard flattens out as you move up the neck for increased playing comfort and speedy articulation.

This bass proudly displays Jackson's distinctive style; all-black hardware, including everything from the bridge to the Hipshot® open-gear locking tuning machines, durable finish, and Jackson's signature pointed 4-in-Line headstock along with a silver "Fallout" 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 USA Signature David Ellefson Concert™ Bass CB IV - and now it can be yours.
