Rotosound Swing Bass 66 RS66LC Stainless Steel Bass Strings - Light Gauge Long Scale | No Limit Guitar Co, Idaho Falls
Rotosound Swing Bass 66 strings are the originals — introduced in 1962 as one of the first round-wound stainless steel bass strings ever made, they set the standard for electric bass tone that players and manufacturers have chased ever since. The RS66LC is the light gauge version of this iconic set, offering the same vibrant tone, great feel, and long string life in a slightly more pliable, easier-playing configuration. Trusted by legends like Geddy Lee, Billy Sheehan, and John Paul Jones, Swing Bass 66 strings remain the benchmark for stainless steel bass strings more than 60 years after their debut.
Product Overview
The RS66LC is a four-string, long-scale set wound in round-wound stainless steel, fitting bass guitars with scale lengths between 32" and 34". Light gauges — .040, .060, .075, and .095 — make this set an excellent choice for players who want the characteristic brightness and punch of Swing Bass 66 strings with reduced string tension, making fretting, bending, and fast technique feel more effortless across the neck.
Stainless steel winding gives Swing Bass 66 strings their signature tonal identity: a bright, cutting attack, strong upper harmonic presence, and a naturally aggressive edge that punches through any mix. Compared to nickel-wound alternatives, stainless steel is harder, more reflective, and more resistant to the oils and dirt that deaden strings over time — contributing to the long string life that Rotosound Swing Bass is known for.
Like all Swing Bass 66 strings, the RS66LC is built around a proprietary steel alloy and a manufacturing process that Rotosound has kept closely guarded since the series launched. It's this combination of exclusive materials and decades of refined craftsmanship that produces a sound and feel that simply cannot be replicated — consistent, vibrant, and unmistakably Rotosound.
Ideal For
- Players transitioning from medium to light gauge strings who want lower tension without sacrificing brightness or bite
- Rock, punk, and progressive bassists who demand cutting, articulate tone that sits above loud stage volumes
- Fingerstyle players and pick bassists who appreciate the lively, responsive feel of lighter stainless steel strings
- Fans of the classic Geddy Lee or Billy Sheehan sound looking to match the strings behind those iconic tones
- Bass players in Idaho Falls searching for light gauge stainless steel bass strings with a legendary track record
Key Features
Light Gauge for Easier Playability, Same Iconic Tone
At .040, .060, .075, and .095, the RS66LC delivers all the brightness, punch, and harmonic richness Swing Bass 66 is known for with less tension across the neck. Lower tension means easier fretting, more comfortable playing over long sessions, and greater ease executing fast runs and intricate techniques — without giving up the aggressive stainless steel character that defines these strings.
Round-Wound Stainless Steel Winding
Stainless steel is brighter, harder, and more durable than nickel winding, producing the crisp attack and vibrant harmonic presence that made Swing Bass 66 strings famous. Round-wound construction adds tactile feel and enhances sustain and brightness, making these strings ideal for players who want their bass to cut and project with authority.
Proprietary Steel Alloy and Closely Guarded Manufacturing Process
Rotosound's specific steel formulation is unique to Swing Bass 66 strings, and the production process behind them has been carefully refined and protected since 1962. This is not an off-the-shelf string — the materials and manufacturing craft behind it are a direct reason these strings continue to outperform and outlast the competition.
Long String Life
The stainless steel winding's natural resistance to corrosion, body oils, and grime means Swing Bass 66 strings retain their brightness and tonal character significantly longer than nickel alternatives. For gigging bassists who want strings that stay fresh through extended use, this durability is a meaningful advantage.
The String Behind Iconic Bass Tones
Geddy Lee, Billy Sheehan, and John Paul Jones are among the most influential and technically demanding bassists in rock history — and all have chosen Swing Bass 66 strings as their go-to. That's not a coincidence. More than 60 years of consistent performance at the highest level is the most convincing endorsement any string can earn.
