You're right, Donny, Paul has done well with it. I just think that particular bass sounds awful and I think it sounds just as bad when Paul plays it. Bass was never the strong part of Beatles music. That tone wouldn't fly today, for sure. i call it the "short scale runs".
At least, that's my opinion. Love Paul, The Beatles and lots of their music. Just don't like that bass or the sound that comes out of it, historic or not.
