I apologize if this question has been asked. My first instructor had me using all 4 fingers on my fretting hand, one finger per fret which seemed like the normal way to play. Then when I changed instructors he told me that was the wrong technique and that you don't use your third finger. That happens to be the method taught in the Hal Leonard bass books. I was just wondering which way do you play, 3 or 4 fingers.
