For you slappers, how hard do you slap? For those of you who do left-hand slapping, do you find it's more effective when it's done lightly or heaviliy? Which do you prefer and why? I've been experimenting with a very light slapping technique lately, and it's been coming out really well on tracks. Does anyone else do this? Who are the bass players you think of when you think of a slap style with a light touch?
