XL Nylon Tapewound bass strings are the warmest, smoothest bass strings we have to offer. Great for fretted or fretless instruments, these flat wound, silky smooth strings have a distinctively warm, percussive tone, with no finger noise. Made with a high carbon steel core and wrapped in flattened black nylon, our Tapewound strings are polished to an ultra-smooth finish, delivering unrivaled punch, depth, and focus. Made for medium scale basses, this 50-105 Medium set has a higher tension, affording increased low-end response and output.
