Silk and Steel were uniquely designed to be our warmest, mellowest acoustic guitar string. Often preferred by folk players, the softened tone of Silk & Steel is ideal for parlor guitars and vintage instruments. Made with silver-plated copper windings, over a combination silk and steel core, the low tension and reduced finger noise of Silk & Steel is well suited for mellow acoustic vibes and fingerstyle playing. This 11-47 Light set is easy to play and provides a warm tone.
