I want to put a whammy bar on (another) bass. This means a Graphtech Tusq XL self-lubricating nut to help it stay in tune. The current nut is 6 mm thick front-to-back; Graphtech makes a lot of thinner nuts. I think a thinner nut would be better for a whammy because there would be less resistance to string movement. Would a thinner nut adversely affect intonation or anything else?
