A hybrid gauge 12-56 for more support without losing comfort
The Light Top/Medium Bottom 12-56 set is designed for acoustic guitarists seeking a soft feel on the treble strings (bending, vibrato, precision in arpeggios) while gaining strength, volume, and bass on the wound strings. Ideal for alternating energetic strumming and nuanced playing, with stable response to both pick and fingers, and optimized lifespan thanks to the XT treatment.
