Freedom Tone Shift Bass Bridge ver. 2.0. The difference from ver. 3.0 is the weight. 2.0 is the heaviest at 231g. Also, 3.0 requires routing, but this 2.0 does not. It can be easily installed on both Jazz Bass and Precision Bass, and you can simply swap it back if you want to return to the original. This makes it safe for vintage instruments. It's used for basses like cheap Precision Basses that sound muddy and lack clarity. If you get a Fender Japan Precision Bass from the Fujigen era cheaply and replace the bridge, the cost performance is outstanding compared to buying a current Fender for 300,000 yen. If you get tired of it, this part is in demand, so you can sell it quickly. It will sell quickly on Digimart, so you can be assured. There is one small scratch on the back, but it's in pretty good condition. Thank you for your interest. Thank you for viewing.
