Even with a well cut nut, staggered inline tuners may not bind, may have good tone, but it's still annoyingly easy to pop a string out of the nut while bending another one. String trees are an afterthought to fix a problem that can't be solved by properly cut nut or staggered tuners.
I may still put on black Tusq tree(s) at some point. Tusq for lubricity, black to stealth it.
