Der OPTIMA Regular Light Satz (2028.RL) liefert dir langlebigen Klang, sauberes Spielgef\u00fchl und zuverl\u00e4ssige Performance \u2013 perfekt f\u00fcr Rhythmus und Lead. F\u00fcr alle, die ihr Instrument ernst nehmen und nicht st\u00e4ndig Saiten wechseln wollen.",
      "full_description": "Nicht jede Saite macht Eindruck.  Diese hier bleibt.\u00a0   Das  OPTIMA 24K Gold Strings 2028.RL Set ist kein Standard-Satz . Das ist Material f\u00fcr Musiker, die wissen, wie sich gute Saiten anf\u00fchlen m\u00fcssen.  Die Diskantsaiten aus vernickeltem Stahl werden mit echtem 24K Gold veredelt. Die Basssaiten setzen auf einen stabilen Sechskantkern mit vergoldeter Umspinnung.   Das Ergebnis:  Ein klarer, stabiler Klang \u2013 auch nach vielen Stunden Spielzeit. Kein Anlaufen. Keine Korrosion. Weniger Wechseln. Die Oberfl\u00e4che f\u00fchlt sich glatt und direkt an. Kein Widerstand, der dich ausbremst.  Der  Regular Light Satz (.010\u2013.046)  gibt dir genau die Balance: Flexibel genug f\u00fcr Lead, stabil genug f\u00fcr Rhythmus. Egal ob du gerade erst anf\u00e4ngst oder seit Jahren spielst \u2013 diese Saiten machen keinen Unterschied zwischen \u201egut genug\u201c und \u201erichtig gut\u201c.   Sie geben dir einfach das zur\u00fcck, was du reinsteckst.   Auch f\u00fcr Nickelallergiker geeignet, da die Oberfl\u00e4che vollst\u00e4ndig durch die Goldbeschichtung gesch\u00fctzt ist. \u00dcber 100 Jahre Erfahrung stecken in diesen Saiten. Aber entscheidend ist nicht die Geschichte.   Sondern das, was passiert, wenn du spielst.",
