[quote name='matski' post='912754' date='Aug 2 2010, 01:20 PM']I replaced the nut on my P bass a couple of months ago and it was a piece of cake.
I bought a Tusq one off the web, used the highly scientific method of gently tapping the old nut out sideways with a hammer and a flathead screwdriver, and slotted the new one straight in.
Maybe I was lucky that the replacement nut was exactly the right size and needed no sanding down to fit, but it couldn't have been simpler.[/quote]
Did it have the string slots already cut?
If so you were lucky that they didn't need adjusting.
Taking the old nut off & fixing the new one in place isn't the tricky bit - cutting the slots properly is.
