I hate to say it, but when I read this, my first thought was how much fun it would be to be in a band w/someone who has three tuners (even two) on his board, and to adjust the caibration on two of them when he's out of the room so they don't agree. Then change them again when he's out again so they disagree differently the next time. Then maybe have the keyboard player detune at the next chance, but have everyone else stay in tune with him.
Funny, nobody's ever called me and asked me to be in a band...
