I play in a Blues/Rock band that does covers, but a lot of original stuff as well, we are currently two guitars, Bass and Drums and will be adding a Keyboard player soon. We have recently started tuning down a 1/2 step to Eb(ala SRV, early Van Halen). I like the change, it seems to add fullness and more bottom end to everything, and since I do almost all the singing, just that 1/2 step down makes a big difference.My other thought is when we add a Keyboard player, it will make them happy, because they love Eb!My other Guitar player is not wild about the change because he says it changes the feel of his guitars too much, and that he will probably have to jump up to a heavier string gauge to compensate. I'd like to hear how some of you feel about this, are there some of you who like to tune down? or not? Would it mess with your guitar too much to do so? What are your thoughts on the advantages/disadvantages of doing this?
