ENR71S's combine the playability of common 45-100 gauged sets with the benefits of an exclusive ''Half Round'' manufacturing process. This set is fit for short scale basses with a string scale length of up to 30 inches. D'Addario Half Round bass strings are wound with pure nickel, then precision ground, leaving the outer surface smooth and semi-flat while retaining the flexibility of round wound strings. D'Addario's exclusive heat treating process ensures that Half Rounds retain their round wound brightness and sustain.
