Two years after this thread faded away gracefully, I found myself playing DB with a singer-songwriter whose previous band had been good-quality session guys. He'd fallen enough on relative hard times that he preferred to use me on bass since I was free.
At the audition and the early rehearsals he loved what I was playing, but my intonation was all over the shop. No matter how carefully I played, I was routinely 'off' the note. It was pretty sickening.
Played our first gig (The Troubadour in Earl's Court) and went down fine with the crowd, but I was still unhappy with my intonation.
Next rehearsal, different day but same old sh*t. I stopped the rehearsal and said we weren't going to play another note until we got the problem sorted out.
After 10 minutes of going in circles, the drummer (a very fine pro musician) asked the guitarist what he had his tuner set to.
