Have an Se Soapbar (first gen.) which has served me well through the years. The pots, knobs, and later the pickups were upgraded years ago, but lately I've been thinking about the benefits of locking tuners. As these come from PRS, they are a drop-in replacement, and I couldn't be happier with the outcome. Faster string changes and better tuning stability makes me wonder why I didn't upgrade to these a long time ago.
