weelittledrummer:you got it.It is what you would get on a normal 12 string.These strings are made especially for the job,as it were.There's no problem there.If I were going to use a different tuning though,on a normal strung guitar,Let's say Open C for example,then I would tune down.Then I Put a cappo on the 3rd possition and do it that fashion.I don't like to tune "up" to a chord.First you break strings,then you got pressure on the neck.Having said that,I dont use Spanish tuning,or a Classical guitar.Sorry to waffle on.I would like to know what kind of stuff you do though.
