Swing Bass 66 Billy Sheehan Custom | 43-110

These strings, custom gauged by Billy Sheehan, provide the time tested Rotosound Swing Bass 66 standard set with two special advantages:

A slightly lighter G provides a more even string to string tension across the neck and makes bending easier.

A heavier E string makes for a tighter low end with increased mass for more volume in the lower register. The 0.110″ gauge also facilitates tuning down to a low ‘D’ without the string bottoming out or loss of intonation.

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 Sheehan

Every Swing Bass 66 string is still hand made by highly skilled engineers on James How’s original machinery. 

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.
