Premium coated bass strings with enhanced durability and tuning stability

The D'Addario XTB45100 bass strings feature a microscopically thin, moisture-repellent coating on every string, designed to preserve tone and feel without compromise. This next-generation XT coating keeps the strings feeling fresh and natural while delivering up to three times the lifespan of uncoated strings.

Crafted from High Carbon New York Steel, the XTB45100 set offers superior break resistance and outstanding tuning stability, even under demanding playing conditions. From core wire production to winding and coating, every step of manufacturing is handled in-house by D’Addario in the USA — ensuring consistent quality and performance.
