New Nut?

[siv]

Question for Tom (or anyone who would know...)

My new to me rosewood hollow t seems to be giving me a bit of a buzzing/muting on the high e and b strings when they're played open. I've tried to tweak the action and truss rod, but I think the nut might be too low and creating the issue.

Do I need a special nut for the BFTS, or will any new cut nut do?

any nut will do.
to check the depth, hold down the string at the third fret. the string needs to just clear the first fret to work. if it's touching the first fret it will probably buzz.
check for debris in the slot also.
also check neck adjustment, if the neck is even slightly back bowed, it will make the nut height a little lower.
