Question here for those who play acoustic guitars--do you ever tune your guitar down a half or even a whole step?? Do you do it that way all the time or just for certain songs? And if you do--what are your reasons for doing so? I've played around with this a little bit and I'm curious to hear what some of you think about it, why you do it, etc. I know why I would do it, just want to get some conversation going on the pros and cons. I know some guitarists rarely stray from a conventional E to E tuning, some use drop D at times, but I don't know of very many who use a whole or half step down as a regular tuning all the time. And...go!
