There were times I had wanted to swap the EXP Coated Phosphor Bronze strings that came with my AEBG with flats or tape. But after giving it a lot of thought, I conclude that I don't want to make my AEBG sounds the same as my electrics. I just didn't like the squeaky finger sound of the stock strings. So I limited my search within the available acoustic strings.
I ended this with Elixir Acoustic Bass String 80/20 Bronze. These strings don't completely remove the finger squeak sound, but noticeably reduce it, as they have smoother feel on fingertips. Seems like, at least IME, the Nanoweb coating technology is proven way better than stock's EXP coating.
