This is a Tone Shift Bridge For Bass by Freedom Custom Guitar Research, a bass bridge. It was installed on a bass I purchased used, so the only items included are the bridge itself and five screws. There are some minor scratches from use. There is also some paint chipping on the back. This will be hidden when installed on a bass, so it shouldn't be a problem. I have installed it on vintage Jazz Basses and Precision Basses, and both had improved sound stability and playability. Please understand that this is a used item before purchasing. If you have any questions, please ask via message before purchasing. I will handle the transaction promptly.
