More and more, I look up songs I want to learn, and the first thing I see is the alternate tuning being used, all strings 1/2 step down, sometimes with one or two strings a whole step, the rest a 1/2 step, drop D, open tunings, etc. Do you thing this is on the rise? Do those of you playing in cover bands find you need to change tunings often, or keep a couple of extra guitars to switch to during sets? If so, what tunings do you keep your guitars in? 1 Standard, a second 1/2 step down, a third drop D for example? One last thought, do you think the alternate tunings are used more to match the singers voice/key or to achieve a tone the guitarist is looking for in the song? Or their tone in general?
