JustStrings.com Phosphor Bronze Acoustic .036, 036PB-1star rating 4LloydNovember 30, 2009I couldn't tell the difference in sound between these and other more expensive strings; maybe you can. I bought a variety of single strings with several brand names, and the JustStrings behaved just fine. No quirks of intonation, the ball windings looked familiar, and overall I liked them.
