I picked up a MIJ 66BB in Candy Apple Red with a mint guard and plain headstock (my least favourite colour.. will probably end up CFM or Sherwood soon...). Got a bridge cover with it, because the guy thought they looked better with them. It fits nice and snug and does look nice. I took it off though.. palm muting and all that jazz.
Spent an hour setting up the bridge. Those grub screws are evil rattling bastards. Used a bit of clear nail polish on it and made sure all the saddles sat flat on the baseplate. the thing isn't buzzing for now at all. Right away, I was thinking "ok this is getting a mastery/staytrem and stat", but I got the buzz out of it and I really like the way the stock bridge sounds and feels. The guy had .09s on it. I am going to go grab some 10s or 11s today and get them set up on it. Need to raise the bridge a tad as well, so I don't fret out past the 12th fret. The guy also hardtailed the vibrato. The spring was tightened and the lock was engaged. Loosened the spring and got it moving. It's going to need a lubing, as it is a tad stiff. Smooth action though. I missed that. My CIJ Mascis had the adjust-o-matic that didn't rock, so the vibrato didn't sound as smooth. Bridge goes back to center and it holds the tuning as well as my Mascis did. We'll see how the stock bridge fares.
P.S. even with the .09s the guy had on it (dude had no clue how to set up offsets), I'm not finding myself knocking the strings out of the saddles. I even tested it with a gypsy swing rhythm riff strummed extra hard with a 3mm stubby. They stayed in their little slots. I also did a Moore/Ranaldo/Cobain style noise freak out with it and the strings still did not pop out. Do people actually have this problem? I don't even think Greg Ginn could play this hard enough to move the strings.
p.s.s As usual the quality of the build is A+. Anyone who is unsure of MIJ/CIJ should just forget about thinking and go get one. I've yet to play a bad Fender Japan model in 20 years of playing. Bridges are wonky, but so are the US ones.
Here's a quick pic from my phone. Don't mind the mess in the jam room. I really need to get at that soon. . . .
Better pics when we get some sunshine as well as a video when I get the time.

In this shitty pic, you can see the bridge cover.

You can see the mint better in this shitty pic!
