7 string bass nut
Been trying to search around for a nut for my 7 string antoniotsai bass. I love this bass and want to get a setup, there is a "chuck" missing from the left side of the b string, slots still hold the string in place but figure I would replace it. Been searching tb and the interwebs and have come up lost, even checked websites like Conklin and so forth with no avail. Any help would be appreciated.
