D'Addario Chromes: C. Just seemed boring. They were used so maybe they were too old. GHS Precision flats: B. Good, but the E and A strings were quieter than the D and G. old Fender: D. Tension was way too stiff. new Fender: A. Perfect in every way! Crisp sound, perfect tension (ML gauge), smooth but not slick or sticky feel, and the gray thread color is classy.
