Hey guys, I need your help. I just ordered my second Warmoth 7 string neck and body. This time, I'm going with a fixed bridge set-up. I want a Graphtec nut, but Warmoth only offers the Floyd or Corian nut for the Super 7 neck. Warmoth will go ahead and prep the nut slot (Gibson dimensions.) I just need to find a nut somewhere and have a luthier install it. My neck width is 1 7/8". Fingerboard is 10" / 16" compound radius. What place(s) can I shop at for a pre-slotted graphite nut for a 7 string? Thanks!
