I just changed out the Sunbeams on my fretless jazz. Put some T I flats on. The sunbeams had a much better maawaaaah sound then the flats But the T I flats had a much smoother sound no finger noise .Now if i could just get the maawaaah without the noise i would be in heaven.. Both sound really good -But i am keeping the TI flats on till i find something that will do both Maaawaah and smooth ......anyone found the magic string ?
