The BCPA4 is probably the most evolved of Martin?s acoustic bass models to date. It is built with a Jumbo 14-fret cutaway body, solid Sitka Spruce top, solid Sapele back and sides, and Indian Rosewood fingerboard. The guitar is outfitted with a Fishman Matrix VT Enhance pickup. The nut measures 1-5/8″ and the scale is 35″. Includes original hardshell case and Martin warranty.
