Hi! I'm finishing a 1958 P-Bass inspired build I described in this thread, and the last thing I have to finish is to get a perfect nut. I picked extra hard bronze as a material for my nut, but I don't want to ruin it and file it too low, so here's my questions: What is the optimal nut slot depth for a bass? There's a "Using Feeler Gauges to Control Nut Slot Depth" guide on StewMac, which mentions a rule: But it looks like this is applicable to a guitar, not the bass - because they recommend add 0.002" for bass strings which naturally have bigger amplitude. I want to try BEAD tuning, but I want to be able to go back to EADG without swapping the nut every time. Would it be a problem to have .045-.105 strings in nut slotted for .065-.135? BONUS QUESTION: What is your preferred way of dealing with P-Bass A-string buzz? Retainers, winding all the way down on the tuner, etc?
