This is a GFS 2 7/32" spaced trem with big brass block. I replaced the stock saddles with GraphTech string saver saddles. Includes trem arm (fits nice and tight with no slop), screws, claw with screws, and springs. I had this installed on a Road Worn Strat and it sounded/felt great. I decided to sell the guitar though, so I put it back to stock. I paid about $45 (with shipping) for the trem, then added the saddles for another $40. It was only on the guitar for about 2 months. $40 shipped/pp to the lower 48 States.
