Hello. I am very new to playing 12 string guitars and i am a little confused with the tuning. Everything appears to be in tune except the high G string on my Ibanez 12 string acoustic. I know i need to tune a full octave up from standard G but when i get to E there is a ton of tension on the string and i fear it will snap. Am i wrong in thinking that i need to go a full octave up? Thanks in advance
I know very little about tuning and bynfar am not an expert. but In tune my 12 string 1 full step flat...
d-instead of e and so forth.

it relieves a tremendous tension on the strings and on the body of the guitar . just capo it up to the key you want. It is a little troublesome for people to play along with you.... but it works for me
