my custom built acoustic (very similar to Avalon/Lowden) has been great with Elixir 12's. It has a 5 piece neck, and was built to be rock solid.
I play almost exclusively in DADGAD. But what's been bothering me is that the 2nd string (B normally, A for my purposes) seems tonally more dead than the rest, as if there werent enough tension on it.
I'm considering moving to 13's as I think this may correct the problem, and give better tone overall. But what I want to know is - what are the implications for the neck? Is any adjustment required for such a small increase, or is it still well within boundaries given that the tuning is lower than concert?
Any advice appreciated.
