I've never been much of a slide player, but got a sudden desire to get better since I'm already trying to fake pedal steel with my B-bender anyway. And, since my most common move is to play an Asus2 shape and bend the B string up to a major third, I thought, well, why not simply tune to open Asus2? Tried it, seems to work great. Not only for using the bender, but because you can play your basic sus2 chord over any minor chord, which, I never really got how to play over minor chords well in an open major tuning. But I thought it was weird that I'm finding nothing much online about open Asus2, or in fact any open sus2 tuning. I'm pretty sure I haven't stumbled onto a brilliant new idea here. Any reason this isn't more of a thing? Is there a similar tuning that accomplishes the same things, but better?
