Perfect pitch is a pain?

Get real. Better yet, please tune your B string. I can tell it's way too sharp!

It really has more to do with the ability to tune then to transpose chords. I watch people use their electronic tuners and not have the clue or the ability to tune right without them.

I'm not knocking them. I'm just lucky I don't need one. I do not purposely try to amaze people with how fast I can tune a guitar by ear. I am actually humbled that I have the ability. Remember, I called it a blessing.
