This is the long discontinued and hard to find saddle for the Kahler 2710 "Killer" tremolo as found on many guitars from the mid to late 80's and early 90's. If it says "2700 Series " on it, this is the saddle you need. Since Kahler is unable to make any more of these Floyd Rose Lic. "Killers" or its parts. I pull these from trades I get and only part out the clean ones for you. The saddle locking screw is not included.
