Zack Hickman recently sent me the bass I made for him back in 2007. I reshaped the neck, made a new lacquered bakelite pickguard, and replaced the old pickups with Lollar's Thunderbirds. Better than ever.
Contoured ash body, maple / rosewood neck, volume / volume / master tone controls, toploader bridge.
See Zack with Josh Ritter and Ray Lamontagne, among others.
