Asking for help as I have zero reference for true depth dimensions. Bought this p bass as a light project, umm ok, turned into a complete rebuild. I need help with the fatory nut channel dimension ? Had a garbage plastic pos wedged and glued in. Channel is deeply gouged from previous owner implanting, took me an hour to remove the super glue. Used a 3/32 wood turning gouge and light chemicals to clean the channel. I'm new to electric basses soooo any help is appreciated where and what best fits the Korean fender p bass originally, this is a 1993 silver edition, wanting to keep it as original as possible...any help is truly appreciated....
