The Martin D-18 Authentic 1937 VTS Adirondack/Mahogany Aged Dreadnought Guitar features an Adirondack spruce top with Vintage Tone System (VTS) and genuine mahogany back and sides, all finished in aged vintage gloss for an authentic, classic look. Built with a dovetail neck joint and hide glue construction, it boasts an authentic 1937 forward-shifted X-brace and scalloped bracing for superior resonance. The guitar's 25.4" scale length and 1 3/4'' fingerboard width provide excellent playability, while the aged ebony bridge and Waverly nickel open-back tuners ensure a vintage feel. Complete with a tortoise pattern pickguard and multi-stripe rosette, this guitar delivers both aesthetic appeal and exceptional sound quality, and it comes with a hardshell case for protection.
