--- Set .009 - .042 --- <.009 .011 .016 .025 .032> Developed and handmade in Germany from the best materials and for the highest tonal requirements. This series reflects our tradition of rope making. The result is a chain of unmatched premium quality. All strings are coated with real 24 carat gold and are therefore completely immune to tarnishing or corrosion. Their durability is up to three times greater than normal ropes and is suitable for people allergic to nickel. The golden strings are characterized by a bright sound and the typical sound of gold, which was also loved by John Entwistle. And of course, also Brian May plays on his OPTIMA GOLD STRINGS guitars.
