Swing Bass 66

This is the stainless steel roundwound string that James How and John Entwistle perfected into what was to become the industry standard. 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

Inspired by the penetrating tone of legends such as John Entwistle and Chris Squire, players worldwide have strung up their bass guitars with Swing Bass 66 strings.

The distinctive sound of our roundwound Swing Bass 66 strings have been used by the bass-world’s biggest hitters such as Jaco Pastorius, Geddy Lee, Billy Sheehan, Noel Redding, Duff McKagan, and John Paul Jones. The bright red silk ends are hard to miss!

A string for everyone

With so many musicians experimenting with unique gauges and drop tunings it is hardly surprising to know that Swing Bass Custom Box Singles, first introduced in the ’60s, enjoy more popularity now than ever before.

With such a wide range starting from 0.025″ to 0.140″ in increments of 0.005″ there will be a gauge to suit everyone’s custom set.

Manufactured in the UK to precise tolerances and using only the finest materials, you can rely on Rotosound strings for consistent tone and performance in every packet.

Iconic music strings

This innovation continues Rotosound’s proud legacy of cutting-edge string design that started with our roundwound strings in the sixties.

Developed in conjunction with some of the world's top artists, Rotosound strings are synonymous with timeless tone, longevity and rock history.

Started in 1958 by James How, an engineer who made strings for his own instruments, Rotosound became known around the world for its superior quality products and famous endorsees such as Jimi Hendrix, Pink Floyd, and Queen to name just a few. The Who’s John Entwistle started a long partnership with James and helped develop the Swing Bass roundwound strings which have become the industry standard.
