Titanium and Titaniumn/Kevlar tailgut wire, designed to offer extra strength to reduce breaking.
VA159/AA159 - All Titanium tailpiece wire with Titanium fittings. The Titanium Tailgut pro is softer and more flexible than steel, wire or nylon and can therefore make it closer fitting to the saddle. This means the sound can be conducted in a broader range of frequency to allow it to be rounder and louder.
CA144/VA144 - Kevlar Loop - A loop of Kevlar with no fittings. Has to be tied into the tailpiece. Length 380mm for cello and 180mm for Violin.
