Description
DR Strings Sunbeam Phosphor Bronze acoustic strings are built on a round core, a construction choice that shapes how these strings behave as they ring out. Rather than sustaining in a straight line and then abruptly falling off — a common trait of many phosphor bronze sets — Sunbeam strings taper off gradually, keeping the tone alive and musical for longer.
That round core also lends the set a notable flexibility under the fingers, making bending and fretting feel smooth while the phosphor bronze wrap delivers the warm, articulate voice this alloy is known for. Expect a tonal character that leans bright and rich rather than dark or muted, with enough clarity to cut through in a mix and enough warmth to hold up in solo acoustic playing.
This set covers a standard light-to-medium gauge spread, giving players a versatile balance of playability and projection:
- 13
- 17
- 26
- 34
- 45
- 56
Whether you’re restringing a workhorse dreadnought or a fingerstyle favorite, Sunbeam Phosphor Bronze strings from DR offer a dependable blend of brightness, sustain, and comfortable feel string after string.
