Dave Mustaine wasn't the only member of Megadeth touting a new signature guitar at this year's NAMM show, the new David Ellefson Signature Kelly Bird Bass was also unveiled at this year's show in Anaheim, California.

The four-string bass features a basswood body with Ellefson's signature red pinstripe finish, bolt-on bound maple neck with 21 jumbo frets and block inlays, EMG pickups, two volume controls and three-band active EQ, Jackson high-mass four-string HM-4 bridge, and Jackson die-cast tuners.

Megadeth are currently working in the studio on their new album. The band are nominated in the "Best Hard Rock/Metal Performance" category at the 55th annual Grammy Awards, which happen February 10 in Los Angeles. See a photo of the bass here.
