I would like to inquire about the best replacement nut options for a Epiphone EB-0 4 string bass guitar model, including brass. 1.48 is the length. width or thickness at 6mm. Height is as 9mm. I did contact Gibson/epiphone and they said go to the local dealer. And I did. That has been over 6 weeks ago. Tired of hearing the Covid19 Scapegoat excuse. Aftermarket replacement nut, much faster and possibly better. The bass came with a plastic nut. brass sounds much more durable, if the right one can be found. The 2 local music stores have limited inventory in bass guitar nut selection.
