Credulity? I could give you a list of 10 songs as an example from just this one particular bassist. As far as him being quoted on the topic of your quote above, im sure the examples of his recordings is the reason why he isnt quoted anywhere on the topic. Its very obvious.
I'm not sure how much studio/recording experience you have, or what it would take in evidence for you to be "proven wrong" but the fact that so many people with an experienced ear were so sure for years he used a P on some recordings, only to find out years later it wasnt a P bass at all, is the point im tryng to make.
So yea, im sure im not the only one that would agree that JPJ would completely disagree with your above statements.
But, these are just my opinions and im sure my audio engineering experience has nothing to do with my "Credulity"
I can go on and provide lists of audio examples, but at this point there is really no need to on my end.
We can agree to disagree.
