Fender's patented 3250L (.009-.042) bullet-end creates a sonic coupling between the string and bridge block, for rock-solid tuning, stability, and increased sustain. Fender has been an instrument of choice for many of the greatest musicians since 1946. Fender's popularity through the generations is a result of their design innovations and commitment to quality. These guitar strings reflect this legacy and are worthy of the Fender name. Attention to detail and the finest materials ensure that you will get the best feeling and greatest sounding strings, set after set.
