I was searching the net for custom truss rod covers and ran across this site, and thought I would share. I need to check with him and see if he will do custom sizes and shapes. Of note, check out Style "A." Seems like Gibson has threatened to sue him for using their truss rod cover shape. It's not like Gibson makes anything this nice for one to customize their Les Paul. Anyway, see here: http://www.luthiersupply.com/pearltrussrodcoverpage.html
