One thing I recently learned about using an electronic tuner for strings -- the tuner works best when it "hears" a fundamental with few overtones, so the "pluck near the bridge" -- which I learned to do when tuning by ear -- has been replaced by "pluck at the 12th fret." Your ear tells you the note you get isn't "rich" enough to use to tune, but the electronic gizmo eats them vibrations up, and gives you a much quicker "result" on the dial.Honest.
