Professional bass player, performing 3-4 nights a week in varying styles. I use these strings on a Fender MIA Jazz Bass and MIM Precision Bass, and they perform very well.
I have always used D'addario strings on both guitar and bass, as I trust the product quality and consistency, and these strings are no exception. I prefer thinner strings on bass with a low action and these stand up very well over a long time. When performing in hot, sweaty environments they last a long time before becoming dull, and hold tuning very well when your instrument is set up correctly.
