I'd like to tune half step flat all the time. To me, It just sounds and feels better. Most of the guys that make me want to play guitar have tuned a half step flat at one point or another. I use hybrid slinky .009 to .046 strings on my main guitar, an American Deluxe Tele. I retune that to open E on a few songs. Another guitar I keep tuned to open G. Another has a locking vibrato bar. I bend the **** out of the strings when I play lead. Sometimes a step and a half+. The bass player (who has exactly one bass) just texted me asking to retune to 440. I do not want to do that but I'm not sure how to go about explaining why. I'm the band leader. Me and the drummer pay the rent on the rehersal space. He doesn't care where I tune We just agreed to bring in a new singer who we've rehersed with 5 or 6 times. He's only commented on one song where it affected his range (Mary Janes Last Dance). I think they actually tune UP a half step, so we're actually playing it a whole step flat. I guess the main reason for posting this is because I like to keep the band strife down to a minimum. I fired our last bass player a few months ago and that SUCKED! I'm going to rehersal in about an hour. I never texted the bass player back. Any advice?
