The titanium bridge clip is designed to extend the contact area between the string and the bridge and reduce the pressure on the upped edge of the bridge, thus protecting it.
Titanium has excellent acoustic energy conduction to transfer sound waves at full frequency which can make a difference to the sound quality and volume of your instrument.
The clip is easily installed and can be stuck to the bridge in the correct position.
The weight of the bridge clip for violin is 0.025g and for cello is 0.05g
