i have been playing the the bass for just over 18mths i've got a few tunes under the belt, but im having prob's with string muting, i play finger style all is ok untill i get the string still ringing (after it has been muted) i use the finger on string and lift off fret method, all is ok untill i move up tempo then i dont have the interval time to damp the strings, what am i doing wrong or is there another method that can be used.
