Optima No.6 GCMT Gold Natural Carbon medium tension.

We have left behind old patterns and old materials and have simply invented the classical guitar string again. The bass strings, made of a completely new core material, wound with a 24 Carat Gold wrapping, result in a string with an extremely fast response and a powerful tone that is sustainable and very rich in overtones, whereby the sound spectrum remains perfectly balanced. The set is completed with our highly praised Natural Carbon treble strings.
