I've gotta get a nut installed on my hopefully soon-to-be-completed strat project. I plan on using the trem, at least a little. I've got the Gotoh Locking Vintage tuners. I though about using a roller nut, but understand they can sound too metallic. Graphite or tusq seem to be the best options to prevent any binding of the string, or maybe the Trem-Nut by GraphTech. Any input one way or the other, or other product suggestions?
