James How, Rotosound's founder, revolutionised the acoustic guitar string with his world acclaimed piano string contact core design. Originally released under the Superwound name ‘Country Gold', these strings employ a wrap wire that stops 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.
Pioneered by Rotosound in 1974, Super Bronze remains the choice for long sustain and brightness. Applying our patented Piano String Design technology to 92/8 phosphor bronze windings offers unrivalled sustain and presence.
