Imo, I think the best repro tuner buttons out there are the Vintage Haven ones from England. Uncle Lou Premiums are a very close second.
The new tuner buttons from Kluson (Korean made) on the 2013 reissues look like crap. Way too transparent and epoxy-like. And the transition edges are way too sharp.
I've had all three on guitars.
The early 1960 posted above seems to have been fitted with Uncle Lou Premium repros, based on the wear and tear on the rest of the guitar and the aging on the tuning machines.
I checked out the Vintage Haven tips and they look lgood but I can't for the life of me figure out how to order them...
WD is out of stock on the Klusons...
