La Bella Criterion C500M Acoustic Guitar Strings, Golden Alloy Medium 13-56

The La Bella Criterion C500M acoustic strings in medium 13-56 gauge are built for players who want full, projecting tone from their acoustic guitar. The golden alloy winding delivers a warm, balanced sound with a bit more sparkle in the highs compared to standard bronze. At medium gauge, these strings offer solid tension that drives the top of your guitar hard, producing big volume and rich overtones.

Medium gauge is the traditional choice for flatpicking, strumming, and bluegrass-style playing where you need your guitar to cut through and fill a room. The Criterion line makes that kind of tone accessible at an everyday price. If you have a dreadnought or jumbo body that thrives on heavier strings, the C500M set will bring out its best qualities. Reliable intonation and a smooth feel make these a practical choice for regular gigging and practice.
