Sorry if this has been asked before, but I was wondering if a tenor would be able to take the extra tension of ADF#B tuning, as I don't want to damage the neck so I'm a bit wary of attempting it.
A string set like South Coast's LML-NW is like medium-light tension and can be tuned to ADF#B without any extra stress on the instrument. In fact, I have just done that on one of my ukes with that exact set of strings.
