Description
Swap your tired, chalky acoustic strings for a set of DR SUNBEAM Phosphor Bronze and hear the difference the moment you strum. Where most phosphor bronze sets sustain in a flat line and then just drop off, Sunbeam’s round core construction lets the note taper naturally, so you get more usable sustain out of every pick or strum instead of a sound that dies mid-chord.
Tonally these are bright without being harsh and rich without going muddy — that sweet spot acoustic players chase when they want warmth on the low end and shimmer up top. They’re also noticeably flexible under the fingers, making bends, fingerstyle runs, and long practice sessions feel easier on your hands than stiffer sets.
This set runs a medium 13-56 gauge spread:
- 13
- 17
- 26
- 34
- 45
- 56
If your current strings sound bright for a day and then go dead by the weekend, it’s time for a fresh set. Keep a spare pack of Sunbeams on hand at StringRush — because a dull acoustic never sounds as good as you remember it.
