I would like to know how easy it is to replace a fender jazz bass nut. I have a Squier that needs a new nut. I filed slots because string height at nut was WAY too high. Now perfect height with flatwound strings, but I have gone back to roundwounds, and the slots are a little too low. Laid tape in slots to get strings to correct height, but this is only temporary fix. I have no problem working on my own instruments, but would like some input from those who have already done it. Does anyone know if the nut in this bass has a flat bottom or a curved bottom? Thought about brass nut, but since only real effect is to open strings, will likely go with something a little easier to work with. Now for your input....GO!
