There are a host of guitar players who tune to DADGAD and have made it part of their signature sound doing so, such as Pierre Bensusan and Laurence Juber .
D'Addario strings have always sounded great in alternate tunings, but it took some getting used to the different feel and tension of a slacked string intended for standard tuning. The new EJ24 True Medium set addresses this by using a smaller core wire in the 3rd, 4th and 5th strings.
These strings have an even-feel tension in both standard and DADGAD tunings. String up your acoustic with the EJ 24 set and DADGAD it.
