Alright, I'm most of the way through building my first guitar. I ordered a lot of the parts from Carvin, including the sperzel tuners. Now I had to order one extra, because I'm building a 7 string guitar. Carvin sent the extra tuner, but not the little nut that screws in top and holds the tuner on the guitar. (See attachment) So what should I do? I thought I should call Carvin but would they even be able to send me just that nut? That seems pretty ridiculous. Do you guys know of anyplace I'd be able to get that one part???
