85/15 Bronze is a unique hybrid winding material. It combines the bright sound of 80/20 bronze with the long - lasting quality of Phosphor Bronze. This makes these strings perfect for all playing styles. The 85/15 Bronze wrap wire is precisely wound around a hexagonally shaped high - carbon steel core. The result is a bright, long - lasting tone with excellent intonation. The EZ890 set has a super light gauge from .009 to .045, offering light tension and great playability. It's ideal for flat - picking solos and light rhythm strumming.

Using these D'Addario EZ890 acoustic guitar strings is easy. First, make sure your guitar is in a stable position. Loosen the old strings and remove them from the tuning pegs and the bridge. Take one of the new strings and thread it through the bridge, then up to the corresponding tuning peg. Wind the string around the peg, making sure it's tight. Tune the string to the right pitch. When playing, these strings' light tension allows for smooth finger movement. As for maintenance, after each playing session, use a clean, dry cloth to wipe the strings. This removes dirt and sweat, which can extend the strings' lifespan. Also, avoid leaving your guitar in extreme temperatures or high - humidity areas. If you notice the tone starts to dull or the strings feel rough, it might be time to replace them.
