Favoured by players who appreciate simplicity and authenticity, natural finishes let the instrument’s craftsmanship and tonewoods speak for themselves. Whether it’s the warm glow of mahogany or the bright shimmer of maple, a natural guitar has a timeless, organic look that never goes out of style. These instruments often feel more connected to their acoustic roots, offering both visual elegance and a sense of purity that appeals to musicians across all genres.. SE. Series.
