Carole kaye has stated several times that intonation on a bass is a waste of time and she pulls all her bridge saddles as far back as she can get them. She claims that she can't hear any intonation issues doing this. Her ears must be better than mine because when I tried this my bass sounded like crap so I invested in a Korg DTR 2000 and now spend inordinate amounts of time tweaking my intonation ;-)

Thanks Joey, great tips (never thought about checking grooves at saddles). Funny, may be Carol tune bending all the time...
