I have a brand new set (never been installed) of Thomastik-Infeld Power Bass Roundwound strings (4 string, long scale.047-.107, EB344) I'm looking to trade for a new set of D'Addario Chromes (flats, .045-.100, long scale). As I said, the TI's are brand new, although the box is a little worn. I might even consider a trade toward a Boss CEB-3 Bass Chorus or an MXR Phase 90...plus a little cash on my part. If you don't have the trade, I'd be willing to sell them for $30 shipped to the lower 48. Thanks!
