I see so bad information being slung around, I would like to suggest to beginners they put aside their slap bass DVDs and go watch Milt Hinton on youtube. This grand old man (now deceased) is the godfather of slap bass. He not only slaps ferociously, he does it with an ease and relaxed demenour that belies what he's playing. Willie Dixon is another old-timer who rules in this dept, but Milt Hinton is king. They didn't call him the "Judge" for nothing. Study the Judge .... you wont regret it.
