Hi.
It depends.
What's exactly wrong with the TR?
Detached anchor point=very bad.
Strippped rod=very bad.
Snapped rod=very bad
Badly seized nut=usually bad.
The nut bottomed out=easy fix.
The nut is stripped=easy fix.
By bad I mean either removing the FB or the skunk stripe is necessary. Or it means that a new neck is in order.
That's my opinion at least

.
