SIT 40-100 Electric Bass Guitar Power Wound Nickel 4 Strings
SIT NR40100L Power Wound Nickel Bass Strings – The Industry Standard for Versatile Tone
The SIT NR40100L Power Wound Nickel Custom Light set is SIT's most popular and widely used bass string series. These round wound strings have earned a well-deserved reputation as the industry standard, trusted by bassists worldwide for their exceptional quality and versatility.
Premium American Craftsmanship
Handcrafted one at a time in Akron, Ohio USA, each string is expertly wound using the revolutionary SIT LevelWrap™ formula. This innovative technique ensures that the cover wrap maintains an exact tension throughout the entire string-making process, guaranteeing optimal playability and tonal consistency.
Balanced, Punchy Tone for Any Style
The Power Wound strings feature a cover wrap that is 8% Nickel-plated steel, providing a smooth feel that's easy on the fingers. This not only enhances the string's longevity but also contributes to its distinctive punchy tone while not losing any warmth. Beneath the cover wrap lies a high-carbon steel hex core, which forms the backbone of the string. This high-quality core further enhances the string's stability, allowing it to withstand the rigors of heavy playing while delivering a powerful low end that resonates with depth and authority.
The Perfect Custom Light Gauge
The Custom Light 40-100 gauge (.040, .060, .080, .100) offers a comfortable feel with balanced tension across all four strings. The Long Scale "Live" winding length of 37.5 inches ensures compatibility with most standard 34" scale bass guitars. Brass-colored ball ends provide a secure and stylish connection.
