So I put a Vega Trem on my main guitar a few weeks back. Sweet unit, but the headstock end wasn't keeping up. I put a Fender LSR roller nut on it today and I simply cannot knock this thing out of tune. I was wondering if maybe I would also have to buy locking tuners, and it's totally not going to be necessary. The problem is completely solved! On another note, I've been pretty scarce here of late because work has become frighteningly busy. But I have a couple of days off, and tonight I'm going to do a few other things to the guitar. Pics coming tomorrow!
