Made in UK since the 50's by one of the largest guitar string manufacturers in the world. Rotosound, used on some of the most amazing albums recorded by some of the best artists in the business. Rotosound makes guitar strings in the piano string design. That is with the wrap wire stopping short of the ball end so that a section of the core wire is exposed and only the core wire comes into contact with the saddle. These strings are called ‘Country Gold’.
