The T3BP features a Nashville small post TOM (Tune-O-matic) bridge, the standard bridge for many USA-made guitars. The saddles are grooved. After adjusting the string height and intonation, the unique, patented "System II" structure secures the bridge body and studs with set screws, eliminating bridge rattle and effectively transmitting string vibrations to the body, improving intonation and sustain. Also, because the bridge is fixed, it will not come off when changing strings, and the intonation and string height before the string change will be maintained. ※Please note※ Please refer to the drawing to confirm the dimensions. If you are unable to install TonePros onto your guitar without any modifications, please consult a music store or repair shop. Forcing the replacement or installation may damage or malfunction the guitar, or may result in unexpected injury. In such cases, please note that we cannot guarantee anything other than defects in TonePros products. ■Color: Chrome ■Radius: Approx. 304.8mm / 12 inches *1st-6th string saddle radius ■Saddle material: Brass ■Wrench: 1.5mm
