Martin commissioned Nub of Nub Grafix, a custom motorcycle painter whose work has been seen on American Chopper, to create a one-of-a-kind guitar for the Austin Summer NAMM show. The dreadnought's theme is Ghost Riders in the Sky; the cacti and hand-gold leafed snakeskin flames are said to represent Texas. Photo by Lynne Margolis.

One of the most stunning new additions to Martin's collection is the OM Negative Orchestra model. Martin's Dick Boak said he came up with the idea for the guitar in the late '90s while looking through old photo negatives. He loved the quality the instruments had as reversed images on the negatives. "To me, it looked like a guitar dressed in a tuxedo," he said. The Negative has a black lacquer finish that makes the white fretboard, bridge, pickguard and headplate boldly stand out. Abalone inlays and herringbone trim further emphasize the guitar's unique look. Photo by Lynne Margolis.

The Martin D-100 Deluxe, based on the millionth guitar the Nazareth, PA., company manufactured, is a limited edition of 50 Brazilian rosewood and top-grade spruce guitars. Martin’s Dick Boak called it “the most extravagant production guitar ever made.” He reported 30 have already been sold, despite the $109,999 price tag. Photo by Lynne Margolis.

Martin's Dick Boak with a one-of-a-kind show guitar featuring unique inlays and a soundport that provides some extra volume for the player. Made of Madagascar rosewood, its light-up, color-changing headstock makes it a “a little quirky.” The lights run on a rechargeable battery and are activated by a switch in the soundport. The guitar retails for $19,999. Photo by Lynne Margolis.
