I purchased this last year and installed it on my Ibanez guitar, but I removed it again because the original part was better, so I am selling it. I used it for one year. There are no particular problems with its use. The box feels a bit old since I bought it last year, but the contents are clean and there are no problems. * When replacing the Floyd Rose, the Tremolo Claw was not included, either because the repair shop forgot to include it or it wasn't originally included. (Photo 9) Please check the parts in the photos before purchasing.
