Jackson Announces New David Ellefson Signature Basses

Jackson® is proud to present new signature offerings for Megadeth’s David Ellefson.

Jackson and Megadeth’s David Ellefson joined forces to bring a fresh new spin on his signature lineup with the 4-string X Series Signature David Ellefson Concert™ Bass CBXM IV and 5-string X Series Signature David Ellefson Concert™ Bass CBXM V. These hard-hitting models are ravishing in look and sound, exquisite in feel and loaded with personal design touches straight from the man himself.

Both models feature a poplar body constructed with an upper contour that provides a comfortably stable anchor for pick or fingerstyle playing alike, and a lower contour for perfect balance when propped on a knee. A graphite-reinforced bolt-on quartersawn maple neck provides the utmost stability for highly-technical lightspeed playing, while the 12”-16” compound radius maple fingerboard has been designed for increased playing comfort and speedy articulation. A heel-mount truss rod thumbwheel also allows for quick and convenient neck adjustments.

Active EMG® J bridge and EMG P neck pickups provide plenty of punchy mid-range and increased output as an active 3-band EQ bolsters their native power, shaping and refining it for maximum impact and versatility. The blend knob mixes the pickups to taste  — add more of the neck pickup for a punch of warmth or bring up the bridge pickup for more cut. A Jackson HiMass™ bridge sharpens notes’ attack for extra clarity, granting enhanced sustain without significantly altering the instrument’s fundamental tone.

The 34”-scale CBXM IV and 35”-scale CBXM V are offered in Gloss Black with white pickguard or Snow White with black pickguard. These leviathan basses are finished off with chrome hardware and an all-new Jackson paddle headstock (CBXM IV has 4 tuners on top; CBXM V has 4 tuners on top and 1 on bottom) that features the familiar “Radiation” logo and Ellefson’s signature embossed on the truss rod cover.
