Brenden, I wouldn't do that. If you have already got the groves in place you can use strings to assist to file the nut. But working from scratch with guitar strings will take you far linger to make the slot and it will be very hard to control getting the slot at exactly the right spot.Quote from Brendan on May 20, 2013, 21:29
My plan for now is to use the supplied strings to file down the grooves - I've got a set of Ernie Balls en route with my bass' name on them...
