I have a Squier P Bass I made into a fretless, and now I am ready to do the finishing touches and get it set up. The plastic nut broke clean in half when I removed it. There is no chipped or cracked plastic. It actually looks perfect and seamless if I hold it together or push it back into its groove on the neck. If I glue it back in place, will that clean break affect sustain or overall tone? This bass has a Badass Bass II bridge, DiMarzio DP127s and a Seymour Duncan Hot Jazz pickup in the bridge spot. With all that tone and output will the nut really matter? If I DO upgrade, though, I will probably get bone from Stew Mac or Ebay. Thoughts?
