Thomastik Acousticore 4-string string set. These were cut and installed on my Epiphone Zenith bass (2+2 headstock) and gently played for one music theatre gig, then taken off. Just enough to stretch them out and break them in a bit. I will add that the Zenith is a strings-through-body bass, so the strings are cut much longer than they would be if the ball ends were seated on top of the body. They should fit any AEB. Note; I originally listed these for $60, but sold them for $40 shipped. http://www.thomastik-infeld.com/family-detail/Acoustic bass
