Fender super bass 7250’s are an excellent all-purpose bass string. They are particularly good for rock, funk, and any style in which the bass needs to cut through. Fender super bass 7250’s combine the high output and dynamic sound of steel with the smooth feel of nickel. The result is a string with bright highs and a thunderous low end. Super bass 7250’s are installed at the factory on all fender US and Mexico basses. - Medium Light
