Babicz Full Contact Hardware® Bridge: Easier adjustment and increased sustain Nothing gives string sustain like a full contact bridge, but it's also easier to adjust for precise intonation and your ideal action. Comprehensive Wood Selection Gibson USA matches the rarest and finest woods to every guitar based on the quality of the match, consistency of the figure, intensity of the figure, clarity, and wave. Thicker Rosewood Fingerboard The increased mass of a thicker, one-piece rosewood fingerboard extends sustain. Pearl Inlays Genuine pearl inlays enhance the guitar's appearance and increase its value. Smoother Sanded, Buffed and Oiled Fingerboard A new, unique oil-treated buffing process upgrades the fingerboard to a silkier feel. Comprehensive Setup A new comprehensive setup and PLEK program combined with a lower fret height on every Gibson USA 2015 Model Year guitar provides a silky smooth feel, accurate intonation, and easy bending. Improved Output Jack The re-designed jack houses a more secure, multipoint connection for better signal transfer and holds cables more firmly in place. Heavier Gauge Wire All Gibson USA guitars now use thicker, stranded wire that provides more surface area for making strong internal connections. New and Improved Hardshell Case The new and improved hardshell case for 2015 upgrades the look and strength. Made to withstand an up to 15-foot drop (up to four times more resistant to drops than other cases), the tough, ergonomic, molded exterior and cushioned interior provide maximum protection as well as insulation from temperature and humidity extremes.
