I'm thinking of doing the following to my Sherman-restored Ibanez UV777GR.
1. adding a set of Schaller mini-locking tuners (to facilitate quicker string changes)
2. refretting with small fret wire (Dingwall uses banjo & mandolin frets claiming it's the ultimate in intonation & overall slick feel. I really dug the feel of the Dingwall basses I tried recently).
Talk me in or out of it.
My 8-string had vintage-sized fretwire and it was sweet.
