Rotosound RS77S 40 - 90 Jazz Monel Flatwound Bass Guitar Strings

Since 1966, these legendary flatwound bass strings have earned their place in music history through the hands of bass icons like Roger Waters, Phil Lynott, Sting, John Deacon, Dee Murrey, and Glen Matlock. The distinctive red silk ends and premium Monel alloy construction create a deeper, fuller tone that maintains exceptional clarity across all playing styles.

Crafted in the UK using James How's original machinery, each Swing Bass 66 string is still hand-made by skilled engineers to precise tolerances. This meticulous manufacturing process ensures consistent tone and performance in every packet, using only the finest materials available.

The secret lies in the Monel 400 alloy – a blend of nickel and copper that provides superior corrosion resistance and a stronger tonal character compared to standard stainless steel alternatives. Jazz Bass flatwound strings offer more resistance under the fingers while producing that coveted vintage sound that has made them the choice of professional bassists worldwide.
