Favorite Guitar Tunings

     So I was just curious, fellow guitarists of spacehey; what is your favorite guitar tunings, and what do you all default to most? I'll start with mine by saying I love Open C (CGCGCE), but sometimes I'll put the high E into a D instead. No reason in particular but I've made some pretty interesting stuff like that. Plus chord building is a bit of a breeze with it being an open tuning. I also really love DADGAD, or DADFAE. There's like, a lot of mysticism of sound behind these if you use them right. I took a lot of inspiration from Devin Townsend and Opeth, so I usually fucks with these tunings lots because of them.
