James How, Rotosound`s founder, revolutionised the acoustic guitar string with his world acclaimed piano string contact core design.
Applied to this acoustic set with 92/8 phosphor bronze windings it offers unrivalled sustain and presence.
Over many years since its inception in the 70`s this string has a loyal following that now numbers many thousands.
A true favourite among players that would not use anything else.
