Zero glide do make a left hand nut but thomman don't stock them so I bought a righty and fitted it to my gretsch electromatic which had that annoying g string out of tune at the 2nd fret problem, basically I filled all the grooves with powdered bone and super glue and recut it as a left hand nut , filled the width to fit the neck and fitted it, it really helps, the action is like having a capo on and now when I play a d it sounds perfectly in tune , if you have problems with your 2nd fret pulling the string out of tune I would recommend this whole heartedly and I can see these really catching on as the whole concept of a zero fret is good
