This lightweight 50s vintage style aluminum tailpiece set features an aluminum body for enhanced resonance, and TonePros' patented locking mechanism securely fastens it to the guitar, transferring string vibrations to the body for improved intonation and sustain. The T1ZSA is a tailpiece set that comes with inch-standard studs and anchors. It is compatible with most USA-made guitars. Also, because the tailpiece is fixed, it will not come off when you change the strings, and the settings 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 ■Stud material: Brass ■Tailpiece material: Aluminum ■Wrench: 1.5mm
