Modern West's signature country-rock sound is rooted in the electric guitar work of Teddy Morgan and Park Chisolm, but Costner and John Coinman back things up with acoustic axes. For Costner that means only one brand. "For forever, I just played whatever anybody put in my hand," he says. "But now I only play Gibson. I'm pretty hard on guitars and they've been really nice to me." To polish his skills before Modern West entered the studio to record Untold Truths, Costner practiced during the long car rides to and from movie and television sets on his weapon of choice, a small-bodied Gibson L-00 Pro that's ideal for traveling troubadours.
