This Martin J-40 (1990), also referred to as the j40 or j-40, is a fine jumbo acoustic from Martin’s golden era of craftsmanship. Renowned for its powerful projection, balanced tone, and elegant appointments, the J-40 stands out as one of Martin’s most impressive jumbo guitars.
Built with a solid Sitka spruce top and East Indian rosewood back and sides, it produces rich lows, articulate mids, and sparkling trebles. The jumbo body size combined with scalloped X-bracing ensures a dynamic, room-filling sound that suits both fingerstyle and strumming.
This guitar has had its binding professionally repaired and is otherwise in good overall condition. It plays beautifully with comfortable action, has no structural issues, and carries the open, resonant voice of a well-aged instrument.
Includes its original Martin hardshell case.
