I was wondering if there is a type of string that is designed for open tunings? Most open tunings are down, but for some like Dashboard Confessional Again I go unnoticed is an open Db5, so the B string is tuned up. But again I was wondering if there is a string that is designed for the stress of open tunings I.E. going from open E to open D. Thanks.
I don't know about that but you could use a capo if the extra tension bothers you.
In general, a lighter gauge string will do those tunings a little easier. But like Chips said, I usually just tune it down a step and capo it up into the right key.
