After over 30 plus yrs of playing i found ive got perfect pitch in my head & havn't used a tuner in years.

I think of Louis Johnson's bass lines in:  
 
Thunder Thumbs and Lightnin' Licks
 
It's been a huge secret,for years and I must say, I never needed a tuner since.  

FWIW, my teach/luthier tunes by ear as well. He tunes to one string and then plays up and down the neck to play around with compensating for fixed temperment. One day I'll have him show me how. He'll tune my guitar to his one string and then goes thru his ritual...he's quick about it and the guitar always sounds great when he does it.
 
For setups and intonation, though, he uses his well-worn Conn Strobotuner.

I find it almost impossible to tune by ear while on stage and everyone else in the band is tuning, adjusting, or just messing around.  My Peterson is always with me.
 
BIll, tgo

good point Bill. Those drummers and guitarists are just too darn loud ;-)

Not the guitarits!   We're perfect!!!!!!  It must be the keys!!! lol
 
Bill, the guitar one

Whenever I play as loud as the drummer, I'm accused of playing too loud.
 
Tempted to just run through the FOH, then it's the soundman's fault (never mind that I trained them).
