I just recently ordered a set of Cleartones Monster Drop C strings (13-70). I was wondering, as I change them, should I tune them straight to drop C or should I still bring them up to standard tuning and then adjust them afterwards?
If they are specifically for a dropped tuning, tuning up to standard might be a risk of breaking your brand new strings.
Perhaps check the packaging to see if they can be used with a standard tuning. If not, don't tune them all the way up.
The point of thicker strings for drop C tuning is that they will end up at about the same tension as the original set at concert pitch. So the neck, bridge and belly of the guitar (and the new set of strings) are only stressed the same as they were originally. Take them up to standard at your peril!!
