A whole 10 sets of D'Addario EJ16 Light (Gauge 12) Acoustic Guitar Strings in Phosphor Bronze give a warm, rich textured tone, slightly more mellow sounding than 80/20 bronze, an even amount of treble and bass tones.

This is a pack with ten sets, which is great for professional players that need to change their strings regularly as they work out cheaper than buying single sets.

The thicknesses are 12, 16, 24, 32, 42, 53.
