There is nothing quite like his late 60's/early 70's tone, for me it started to go away a little when he moved towards more specialised instruments - to my mind in the mid-late 60's he was teasing better tones of out his Precisions than most players were 10 years later getting out of their Alembics - and his skill and creativity on what many consider quite a crude instrument puts him and Jamerson in the same camp; genius creative technicians, in short virtuosos. Yep, there were other good players, Macca was solid and had some lovely lyrical moments, Jaco was the Paganini of bass but a very acquired taste musically, and then...... well who else was there in the late 60's/early 70's? OK, loads of highly competent touring and session players, but Entwistle was one of a very small band of bass players who turned bass into a virtuoso instrument.
