The EXL120BT Medium Electric Guitar Strings are part of the D'Addario Balanced Tension Series that are comprised of mathematically optimized string gauge combinations, resulting in greater control and playing comfort. Combined with the distinctive bright tone of XL nickel wound strings, each set offers greater dynamic control and a more consistent feel between strings for evenly balanced bending, strumming, fretting, picking, plucking and slapping. EXL120BT gauges range from 9-40. 

XL Nickel Wound, D'Addario's most popular electric guitar strings, are precision wound with nickel-plated steel onto a carefully drawn, hexagonally shaped, high carbon steel core. The result, strings with long-lasting, distinctive bright tone and excellent intonation, is ideal for the widest variety of guitars and musical styles.
