Optima No.6 24k Gold Strings Nylon High concert guitar string set set Optima No.6 24k Gold Strings Nylon High Optima No.6 - Every concert guitarist has to remember this name, because these strings are a completely new dimension. Optima has left old patterns and old materials behind and simply reinvented the concert guitar string. The bass strings, from a completely new core material, optionally spun with a 24k gold winding or special silver, result in a string with an extremely fast speech, strong tone, which is very sustainable and rich in overtones. The sound spectrum remains completely balanced. The sentence is rounded harmoniously by either Clear Nylon, or the highly praised natural carbon discants.
