I've been playing bass every now and then for a long time, but not really worked at being proficient. Now, playing bass in a rock band, I generally use a pick, but every now and then, use my fingers. ..
I can get a good even sound using my forefinger - James Jamerson style - but when I introduce my second and third fingers I get extraneous noises of nails etc and a different tone from each finger. What am I doing wrong?
