All the famous bassist mentioned dont have bad technique,its SUPPOSEDLY improper.Who cares how it looks when theyre playing?As long as the end result is a good sounding track that they lay down.EVERYONE,I MEAN EVERYONE on this forum ,name ONE bassist that has ABSOLUTLEY FLAWLESS TECHNIQUE.Im not talking the best technique,Im talking FLAWLESS. I personally listen to a sh!tload of bassist with a varying array of styles and Ive come up with a conclusion.All of them are human(with the exception Victor.haha).I personally think if you are physically comfortable playing your instrument and what you are playing sounds good to you and your bands ear,then you have good technique.But I do agree if you play yor instrument the right way(ie.,proper technique),you are able to do more musically with it.Yes ,Jamerson might have had bad technique,but,DAMN!!I sure wish I had his feel and absolute mastery of the all elusive thing us bassist are after.THE ALMIGHTY GROOVE.Then again,it all comes down to this,I could be wrong,remember were only human.
