PG's Joe Coffey is On Location in Nashville, TN, for Summer NAMM '09 where he visits the Martin Guitars booth. In this segment, we get to see two of Martin's newest guitar offerings, the D12 David Crosby and a Marty Robbins model. The D12 David Crosby is built from specs on a guitar David had altered from a standard 6-string to a 12-string. The D12 features D14 body style, mahogany back and sides and spruce top and a David Crosby signature between the 16th and 17th fret. The Marty Robbins model is made with Adirondack spruce top and has custom inlays including one of Texas to commemorate Marty Robbin's love for big "T".
