I don't.
Why do P Bass guys always seem to need to justify the P bass? Yes, Jamerson was awesome and a P bass in the right context, sounds great to me, but I find them a bit limiting.
There are more tones to a p bass than one thinks, entwistle and wetton pulled off the nice grindy tone, dave hope of kansas had a unique almost rickenbacker tone with his p bass, and jameson had depth. Even though these are different players, the instrument and amplification and ultimately the mind and hands dictate what you can yank outta a p bass or any bass really. The only limiting factor is what you believe the instrument is only capable of achieving.
