Okay, this is a really long shot......... Today, I got hold of a replica 11-string lute. Only thing is: I have no idea how I should string it, and what tuning I should have. It's got an 18.5" scale length, and I've been told to keep the tension as low as possible while still being playable. Any ideas? Or should I just take it to a music shop and get them to do it? Because I really don't have a clue.
