Megadeth’s David Ellefson sat down with Jackson to share the backstory and run down the specs of his all-new X Series Signature David Ellefson 30th Anniversary Concert™ Bass CBX IV model.

“To commemorate the 30th anniversary of our Megadeth album Rust in Peace and to celebrate my long-lasting relationship with Jackson, we decided to feature 4-string companion to the 5-string we released earlier this year,” explained Ellefson. “This bass truly represents the origin story of my relationship with Jackson guitars, tracing back to the late 1980s when the company built me my very first Quicksilver Concert Bass, just like this one!

“Right down to the feel of the body and the neck, the layout of the controls and its thundering rich tone, this bass is a modern representation of that exact same instrument of yesteryear,” said Ellefson. “By revisiting our past, I’d say we created an even better instrument for today.”

The CBX IV features a poplar body with ergonomic contours, through-body quartersawn maple neck with scarf joint and graphite-reinforcement rods, 12”-16” compound radius laurel fingerboard, EMG® P and EMG J bridge and neck pickups, three-way toggle switch, single volume control, old-school two-band EQ , Jackson HiMass™ 4-string bridge and more.
