The guys who really impress me are the ones who can hear a problem mid-song on stage, know right away which string it is and can tune it while playing the song. I've seen it many times and never could figure it out. I saw Yngwie do it several times, but then he plays old Strats and is pretty hard on them. Pretty sure I've also seen Eric Johnson tuning his guitar between songs and mid-song with no tuner.
