DR RCA-13 13-56 Medium Gauge Sunbeam Acoustic Guitar Strings

DR RCA-13 Sunbeam Acoustic Guitar Strings – Medium (13–56)

DR Sunbeam RCA-13 Medium strings deliver bold acoustic tone with a warm, vintage-inspired character and a smooth, flexible feel. Built with DR’s round core construction and phosphor bronze wrap, Sunbeams vibrate more freely than traditional hex core strings, producing enhanced harmonic richness and natural sustain.

The 13–56 medium gauge offers increased tension, volume, and headroom—ideal for strong strummers, flatpickers, and players who want maximum projection and low-end presence. Despite the heavier gauge, the round core design keeps the feel more supple and responsive than many medium sets.

Expect full-bodied lows, focused mids, and clear, singing highs with excellent dynamic range.
