Martin Steel String Backpacker For their size, Martin Backpacker guitars have a surprisingly rich and loud tone, due primarily to the combination of a lightly braced solid tonewood top with a solid mahogany neck, back and sides. Light as a feather, this is a guitar that you can take with you literally anywhere without getting weighed down, plus it takes up almost no room when slipped into its nylon carrying case (included) or strapped around your shoulders. Despite its lightweight character, the Martin Backpacker is ruggedly built to withstand the rigors of outdoor situations like camping, hiking and summer music festivals -- the ideal travel companion!
