I have 2 sets of flatwound strings. Sadowsky flatwounds. These were used and installed on my Precision bass for about a week. They were strung through the bridge not the body. I have removed them carefully and re-packaged them in the original packaging. I am asking $20 shipped. DR Hi Beam Flatwounds: The low E string broke and DR sent me a replacement. So the E string is brand new and unused and the rest of the strings have been used but were only on the bass for about a week. I have carefully removed them and re-packaged them in the original packaging. I'm asking $20 shipped.
