12 string question: what gauge for octave g tuned to unison?

[angus_old]

if i want to tune my octave g string to unison so it won't break, should i use a heavier gauge than the .008 or 9 that comes in the sets?

[DeepEnd]

Yes. Otherwise, the lighter G will end up being too loose and "twangy." Try tuning one of the other strings an octave flat to see what I mean. Many music stores sell individual strings. The local mom-and-pop sells individual d'Addario's. Just buy another string the same gauge as the larger G string. Be aware that you may have to have the slot in the nut enlarged if youi're going to do this.

I guess if you were going to tune it unison you should use an 0.023 just like the main string, but of course you are going to have to file the nut slot, then you are committed to staying with this.

 

But I don't understand why you break octave G's. I use Elixer lights (also a 0.009) and never break a string (but I do tune down and my nut was cut for this string set). You might consider going up to an 0.010 which is what some Light sets use for the G.

 

btw - my project for tonight is to make the nut for my new 12. Should be playing it by the weekend.

Another thing you might try is to buy another octave "A" string and put it on as an octave "G." If you are useing lights the octave "A" is not wound so you may not have to cut on the nut.

I´m experimenting with two 0,17s G strings (electric guitar type) in unison, so far sounds great
