The bright, punchy, high-energy sound of Swing Bass 66 strings is a major part of early rock music history and brought the bass player from the back line to the front of the stage.For the players
“They really sound great, there’s a real organic feel to them, I’ve been to the factory where they’re hand making them…

“It’s such a part of the tone of everything I do!”

“I’m a finger player and when my fingers grip the string the edges on the Rotosound’s, because they’re hand wound, grip really strongly so I can get a really good snap of power out of each note.”
– Billy SheehanA string for everyone
