D'Addario XSB45105 Bass guitar strings

Coated Bass Strings Built for Long Life and Clear Tone

The D'Addario XSB45105 is a 4-string electric bass string set designed for players who want the warmth of nickel-plated steel without the short lifespan of uncoated strings. Its ultra-thin XS coating protects the round-wound wrap wire from sweat, dirt, and grime, while the NY High Carbon Steel hex core holds tuning and resists breakage under heavy playing. This 45-105 Light Top/Medium Bottom configuration pairs a tighter low end with a bright, articulate top, making it a flexible choice across rock, pop, funk, and jazz styles. Made in D'Addario's New York production facility, the set ships in a resealable VCI bag that doubles as a Players Circle registration code.

Who It's For

The XSB45105 is the right choice for long-scale 4-string bass players who gig frequently and need strings that hold tone through sweaty shows and long rehearsal weeks. Fingerstyle players will appreciate the deep, rich response from the medium-bottom strings, while pick players get enough zing from the lighter top strings to cut through a mix. The ultra-thin coating addresses the classic trade-off of coated bass strings — reduced string noise and silky playability without the dull, dark tone that thicker coatings can introduce. Bassists switching from uncoated nickel or steel sets will find a familiar feel with noticeably extended life between changes.
