What is the narrowest string spacing any of the luthiers here have tried/ built? Curious to see how narrow of a 5 string neck I can get away with. As I stated in my Out of the box thinking thread, I tend to finger pluck my strings rather hard, so I will need a little vibrating room Is there a theory or rule of thumb I can apply to designing bass neck width at the nut and body or 22nd fret? I like the feel of a narrow neck. Thanks in advance.
