I've been using the Fender 7250/5-M strings on my bass, and I must say they provide a well-rounded sound. The crisp and bright tone is noticeable, with good clarity that seems to last. I've found the strings to be smooth and playable, allowing for rapid finger movement without fatigue. The sustain is also satisfactory, adding to the overall sound quality. However, I did notice a slight increase in sliding noise compared to other brands. Overall, I'm pleased with the sound and quality, finding them to be a good match for my instrument. The strings have a rich tone with growling mids and a good low end, making them suitable for various playing styles.
