The Maritime SWS HG, as with all SWS models, features all solid wood construction with a Select Pressure Tested solid spruce top and solid mahogany back & sides. The Maritime SWS HG also features a high-gloss Custom Polished Finish. This 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.
