The first day I installed these strings, I wanted to throw my entire bass to the garbage. Three days later, I don't want to change them for any reason! You just have to get a little used to them, and probably change your settings - I inverted the tone and pickup settings on my bass compared to how I used to have them with the previous strings. It is impossible o describe a sound through words, but it has to do a lot with the way you play, too. My bass action is set extra-low as I like to play fingers-down, Richard Bona style, and my sound has changed to the better. Another pro, is that the tension is seriously lowered, so I use less power on my left hand, allowing me to play "just by the strings"...
Would definitely recommend trying!
