I don't really have any criteria for what I think is "good" . Some of my goodest players have got it all ,time tone technique harmony, players like Ray Brown, Jamerson you know the type . I also think Dee Dee Ramone and his shall we say rugged technique is good, sometimes that school band punk rock n roll thing does it for me. but I also like modern nashville players whose note placement and length is exquisite even though their lines through the changes are generic and cliched. Some of the modern gospel players are right show offs but I think they're good too.
is there a bit of a chops vs subtlety thing going on here.
It's all good
