The Maritime SWS Mahogany Burnt Umber GT, as with all SWS models, features all solid wood construction with a Select Pressure Tested solid spruce top and solid mahogany back & sides. This model features the stunning, rich & vintage look of its Burnt Umber finish, with a Gloss Top (GT) & the beautiful satin sheen of semi-gloss back & sides. Our Custom Polished Finish provides excellent protection but at the same time is extremely light and elastic. This is a crucial point in both the sound of the guitar and its ability to age – a thick finish muffles a guitar’s vibration and blocks aging. This model includes EQ onboard preamp. The EQ onboard preamp is dedicated to providing maximum value in a small footprint. This preamp system features volume, tone shaping, and phase controls as well as a low battery indicator.
