I'm curious to see where this goes - I got a great deal on an SC245 last year because the previous owner botched pulling off the old tuners, and there was a superficial crack in the wood near the low E tuner. He sealed it and it didn't look bad from 2 feet away, and I got an awesome deal. That's become my main Les Paul-style guitar that I play out now because it's already defective, so I don't care if it gets wear and tear now.
I had my setup guy give it a once over and install the Planet Waves Auto-Trim Locking Tuners on it. He said they were NOT a direct replacement, and so I now have new holes drilled and exposed ones on the back sitting unfilled. As I said, the headstock already had a defect, so I don't care, but I've been scared to put these on any of my other guitars because I don't want new holes / exposed holes.
I will say, these tuners are the best - the gear and tuning motion is all very smooth, they hold tune well on strings both during a session and over the long haul. The locking mechanism is very easy to move and the auto-trim is AWESOME. On a guitar like this, without a trem, a string change can seriously be done in a couple of minutes with no tools.
