Classic icons like James Jamerson(P Bass),
Jaco,Marcus Miller (Jazz Bass)
made a handfull of bass styles into "the standard"..
and from that point on, they're known as "The best" to dealers,young players..
(I remember as a young guitar player,tons of older guys telling me,"The Les Paul is THE BEST")
..why else would we still see a ton of Hofner "violin basses" on Ebay every day?
After they become elevated to a "classic" level,they become collectable,and sell for $50,000
(even though they sold for $179 when they first came out)
A Jaguar,Pedulla,Dingwall,Ritter,Sadowsky,Citron, or even a Peavey,Carvin or Washburn may be a fantastically created instrument,with great tone and far more features than a PBass...
But as far as popularity,
they'll all always play,"second fiddle" to the classics.
