Not an exclusive "hook" player but primarily play with one finger as much as possible. There are times when alternating feels right and I do it without thinking about it......it kind of finds is spots on its own. I use the floating thumb exclusively though.......comes from good teaching during my mandolin days, no anchoring. Cool story.......my band recently replaced our long time, now retired, guitarist. After the second rehearsal he commented "love the Jamerson technique" how lucky am I to play with a great guitar player that knows about Jamerson and respects his style! Next rehearsal I showed up with my 62AVRI and it's been the number 1 gigging bass for December, January and this far into February. Probably a coincidence........I alternate two in spurts.
