Yesterday, the guitarist and I decided to start tuning everything down 1/2 step for several reasons: many of the artists who we cover recorded that way, it fits both our vocal ranges better, and it makes our instruments feel better. While I keep a 5 string with flats on hand for a few songs and as a backup, I mainly play 6 string and wrote several songs that require 6 strings. I use DR Fat Beams in standard tuning, but unless they just recently released them, they don't come any heavier than a .125 set. For half step down, I would prefer to use a .130 set. Even if I stick with DR, there's enough variety to be confusing. I like a punchy string with some natural brightness to let harmonics ring out. I'm thinking either High Beams or DDTs will serve me well, but Sun Beams and Pure Blues also look good. Any experience with these sets? What would you use for 1/2 step down tuning?
