648 : Even better than the flatwounds? Yes!

Many fanzines and people recommend those strings to install on a fretless bass to sound more like a contrabass. My 500/1 Hofner Beatles bass is a fretted version. As you might remember Paul McCartney used those strings on the Let it Be / Get Back Sessions and the Abbey Road record on his fretted violin Hofner Bass. Those strings are thicker than others, but do not be afraid of that they fit perfect on the bass and they can be played very comfortable indeed. McCartney used the black nylons by Rotosound. They are contrary to the pyramids as you have to file the saddle. Compared to the Daddario ones which tend to burst the nylon wiring those strings are really unique, sound more warm, more contrabass. Put them on your bass and test them and get comfortable with them.
