The Maritime SWS Mahogany Burnt Umber GT, as with all SWS models, is constructed entirely of solid woods. Press-selected solid spruce top with solid mahogany back and sides. This model has a stunning and vintage look due to its Burnt Umber finish, with a gloss top (GT) and satin back and sides. Our Custom polished finish provides excellent protection but at the same time is extremely light and stretchy. This is a crucial point in both the guitar's sound and its ability to age: a thick finish dampens the guitar's vibration and does not allow it to age properly. This model includes built-in Fishman Presys II electronics.
