I picked up this tuning from Soundgarden's song "4th of July", and I like it a lot. The guitar counterpart C-F-C-G-B-E is also interesting to me (and somewhat absurd since the two highest strings are a half step off from most of the others), and I'm playing around with both. I was curious as to whether anyone else here had tried this tuning, or a similar tuning that leans heavily on fifths.
