The Maritime SWS SG, 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 SG also features a semi-gloss Custom Polished Finish with a beautiful satin sheen. 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. This model includes Godin Quantum IT electronics with built-in tuner.
