Newly acquired Taylor 310ce, 2011 model bought from local music shop. Proceeded to put new strings (Elixir nanoweb 0.013-053) on it, and noticed that the low E was dull sounding, dead, little sustain, wimpy sound. Whereas the A and other strings all sounded good. After reading others' comments here and elsewhere, I loosened the E string and re-seated the ball end at the pin. Even though it wasn't obvious that it was not well-seated, this fixed the problem and the E now sounds as it should, with brightness and bass and loudness as expected. Though I'd share this story because others may have the same issue - not the saddle at all, not the nut, etc. - merely the seating under the pin. Surprising but true. And I love the 310ce, wonderful guitar!
