The finish on yours looks in great nick!
I think mine has the original finish and it hasn't had any irreversible surgery, but it did come with a Badass bridge and replacement tuners (individual Kluson types, not Grovers, thankfully). I also changed the pickup, but I'm planning to put it back to something like original spec. It's got a Pigtail bridge at the moment but I've bought an aged "lightning bar" bridge, compensated for a plain third string.
How do you find the Maestro?
