Signature SetsThese 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 playersThey really sound great, theres a real organic feel to them, Ive been to the factory where theyre hand making themIts such a part of the tone of everything I do!Im a finger player and when my fingers grip the string the edges on the Rotosounds, because theyre hand wound, grip really strongly so I can get a really good snap of power out of each note.A string for everyoneWith 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 everyones custom set.Great British qualityManufactured 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.Every Swing Bass 66 string is manufactured on custom built machines designed and built in the UK by Jason How.Iconic music stringsThis innovation continues Rotosounds 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.
