Interesting article
I've noticed as time has gone on (and I've not been playing that long, about 7 or 8 years) that my reliance on what the tuner says is in tune has diminished and I just go by what sounds right. I play extended range instruments mainly; I've a couple of Ibanez 7's and one of their 8's too. And especially with the lower tuned strings I have to aim slightly flat when tuning to compensate for the raise in pitch once the strings have energy. Not that I'm an aggressive picker, mind. I know people who have picked my guitars up and made them sound terribly out of tune purely because they dig in so much.
Another thing I notice is the G string - what the hell is it with that string that it can be perfect in an open chord, and sound like ass when played higher up? Even on a well intonated guitar?
But yes, a good article. I'll try this method out next time I retune!
