Fender SubSonic 9050 Stainless Flatwound Bass Strings (45-105)

Fender SubSonic 9050 Stainless Steel Flatwound 9050CL bass strings are all about smooth feel, warm tone and classic character. With a comfortable 45-105 gauge set and a mellow, rounded sound that sits perfectly in the mix, they are ideal for players who want vintage-inspired flatwound response with modern consistency and reliability.

Whether you are laying down deep reggae grooves, walking jazz lines or holding down soulful R&B, these flatwounds keep things controlled and musical. The stainless steel construction delivers a focused low end with clear definition, while the flatwound finish keeps finger noise to a minimum and feels silky under the hands. Made in the USA and designed for 34" scale basses, they are a dependable choice for both studio and stage.

Fender have also made life easier when it comes to string changes. Classic Fender coloured ball ends help you identify each string at a glance, while silk wraps at the tuner end help protect the windings as you bring them up to pitch. If you are looking to tame brightness, reduce squeak and get a more controlled, old-school bass voice, the 9050CL set is a simple upgrade that can transform the feel and sound of your instrument.

Classic flatwound feel

The flatwound construction gives these strings a smooth, almost glassy surface that feels great under the fingers. Sliding between notes is effortless, vibrato feels controlled and comfortable, and long sessions are less fatiguing compared to brighter, rougher roundwounds.

Warm, mellow tone

SubSonic 9050 strings are voiced for a rich, rounded sound with a strong fundamental and controlled overtones. This makes them perfect when you want a supportive, musical low end that does not dominate the mix, from jazz and reggae through to country and R&B.

Low finger noise

The flat outer wrap dramatically reduces string squeak and handling noise, which is especially useful for recording and quieter stages. Your slides and position shifts stay smooth and discreet, helping your lines sound more polished and professional.

Reliable Fender design

With coloured ball ends for quick identification and silk wraps at the tuner post to help protect the windings, these strings are designed to be practical as well as musical. Made in the USA to Fender’s exacting standards, they offer consistent performance from set to set.
