Description
The D’Addario PB045 Phosphor Bronze Wound Acoustic Guitar Single String is a .045 gauge replacement for acoustic players who need a dependable low string with warm, articulate tone. Ideal for repairing a broken A string, building a custom set or adding a little extra body for altered tunings, it suits gigging guitarists, teachers, students and techs who want consistent feel and reliable performance. The phosphor bronze wrap delivers the familiar blend of brightness and warmth that sits well in strummed accompaniments and fingerstyle parts, while the solid ball end and precise winding provide stable tuning. Keep a spare in your case so rehearsals, lessons and sessions can continue without interruption.
Built around a resilient steel core with a phosphor bronze winding, the PB045 offers a smooth surface and strong, focused fundamentals with rich overtones. The gauge provides a confident feel under the picking hand without feeling stiff, rewarding both light fingerstyle and more energetic strumming. Compared with basic student strings, it holds pitch more securely, maintains intonation up the neck and resists tarnish from everyday play. Response is even across dynamics, so quiet passages remain clear and louder strums project without harshness. It is a dependable step up for players who value longevity and tone, and who prefer the balanced character that phosphor bronze brings to an acoustic guitar.
For school and tuition settings, this single string keeps costs sensible by replacing only what you need, which is perfect for busy departments and learners between grades. Teachers can rely on quick restringing thanks to the stable ball end and predictable tension, helping students get back to scales, repertoire and ensemble work with minimal downtime. It is equally at home in regular practice, open mic sets and weekend gigs, offering consistent feel from session to session. Whether you are matching an existing set or tailoring a heavier bass response, the PB045 gives practical value and musical results, making it an easy recommendation for classrooms, practice rooms and home studios across the UK.
