In honor of the Mule's new album, 'Shout!' we're partnering with our friends at Ultimate Classic Rock to give away one of Haynes' signature Washburn WSD5240 acoustic guitars. Modeled after the original 1937 Washburn Solo Deluxe, these beauties retail for $599, and one look at the solid spruce top, mahogany neck, rosewood sides and back and ebony fingerboard should tell you why. Better still: When our one lucky winner claims his or her prize, they'll own a guitar Haynes will have played and autographed on Sept. 25, 2013, when he's scheduled to stop by our NYC headquarters for a live video session.
