I am getting a 12 string soon, and I use D standard and drop C a lot on my 6 string right now. I went to a local guitar center and tried the guitar I am going to get, and it had 10-48 or something close to it. I went to D standard, and it felt loose. I found out elixir made 12s for 12 string, and I was wondering if it is safe to tune those to D standard and drop C. I don't plan on going up to E standard, as I could use my capo.
D might be as low as you can go without the strings getting too loose
