If it's my six string, it usually stays in BEADGC, although occasionally I might tune the low B down to A. For four string, nearly always EADG but I might occasionally use Drop D.
For solo gigs, mainly standard tuned 6 string, but I do use a couple of altered tunings - CEADGC, CEACGC and AEACGA and occasionally a capo.
The Ashbory takes far too long to retune so stays in EADG (although if you pop the E string out of the nut, you can get a nice open C )
Cheers,
