I have an older mockingbird that came with a special, but a previous owner swapped a 1000 series onto. The first thing I noticed was that there was a good amount of play in the bar, no matter how much I tightened it up. Replaced the bar and coupler with a new OFR one and it’s perfect now. I also had some issues with it returning to zero, so I checked the knife edges. They look pretty seriously worn. The old chapstick trick has it working pretty well, but I have a feeling that, if I replaced the base plate with an OFR one, it would take me decades to get to this level of wear on it.Definitely floyd 1000 series, but i have a couple guitars with those and played many others with them and they really aren't performing any differently than the German ones. Hell, the few specials I've played worked just fine
That’s the best part about the Floyd 1000 and Kahler Hybrid honestly. They both are dimensionally identical to the flagship model, so, if you have an issue with a part, you can reliably find replacement parts, and they’re the same ones you would use in the flagship, so you arguably get a small upgrade in the process.
