Brand new D'Addario EXL170 Nickel Roundwound strings, unopened package. I bought several sets of these but recently changed to different strings, so I never used them. Gauges are .045,.065,.080,.100. This set is identical to what comes standard on Musicman basses, only they last about 3 times as long as the Ernie Ball strings IME. These strings are bright and very responsive, perfect for funk, rock, slap...any style requiring some bite and good attack. $15 including postage within continental USA.
