I have a Micheal Kelly acousitc fretless 5 string. Its not the best made bass, but it works fine as a first fretless for experimentation. The roundwound phoshpor bronze strings that came with it were immediately tearing up the fretboard. I got some Rotosound 77 flats and they sounded a lot better, but I think those strings are made for an electric bass. Any suggestions as to which flats I can get the most volume from for an acoustic? And also, the B string is hardly playable at the first few positions, I was thinking of stringing it up EADGC to play more melodic lines. Has anyone tried this and where can I get a single C string? Any ideas or opinions appreciated!
