Nice finish on the gold. Great retro look with the Butterbean style keys. Precise movement stays in tune well. I had to enlarge the holes Sligh with a drill, but overall installation was easy.
No problem with Grover tuners at all, but they publish that the bushings will fit most guitars. This may be true, but they should let you know which guitars they will and will not fit. They do not fit Fender or Gretsch guitars, so you will need to go to Stewmac to purchase the 10.5mm bushings required.
