It looks to me that in all the videos I saw the famous bass players rake all the time. Are you aware of any famous bassists who strictly alternate/alternated? Also, all of them seem to rest their thumb on E/pickup. Some of them mute with 3 and 4, like Jacco Pastorius or Nate Watts. But the rest do not seem to worry too much about muting A. Are there any greats that play with anchor thumb or floating thumb?
