Description Product Description Martin's largest acoustic body size, the Grand Jumbo, is combined with solid sycamore back, sides and neck, and a Sitka spruce top with Martin's new Vintage Tone System (VTS) that boasts uniquely shaped top bracing that introduces non-scalloped 5/16" X-braces with graduated scalloped tone bars.

Comes equipped with D-TAR Wave-length Multi-Source electronics and bears an interior label individually numbered in sequence and personally signed by C. F. Martin IV. The new Martin Vintage Tone System (VTS) uses a unique recipe that is based on the historic torrefaction system. The VTS acts much like a time machine in which Martin can target certain time periods and age the top/braces to that era. This focused method allows Martin's craftsmen and women to recreate not only the pleasing visual aesthetics of a vintage guitar, but also reproduce the special tones previously reserved for vintage instruments.
