There was a beautiful old maple F50 on ebay a while back, but the serial numbers were filed off. I wouldn't give 50 bucks for any guitar with the serial numbers ground off. What a bad vibe knowing some guy (or Bonnie Raitt, but I repeat myself) had his guitar ripped off, and your money went into the chain of exchange leading back to the theif. If nobody bought hot guitars, fewer of us would have them ripped off. Or am I nuts?
