A P bass has 1 pickup and 1 tone control. It sits in just about any mix perfectly, and a good player can coax MANY sounds out of it - but as for the bass itself, it IS a one trick pony. If a bassist can get 500 different sounds out of a P by using different techniques, that player can get 2000 out of jazz. They can get an infinite number out of Big Al, or just about any other active bass with more than a single pickup. There are versatile basses. There are versatile players. A P bass is the LEAST versatile bass someone can purchase. It does one thing, with limited variation (the tone control). It does that one thing excellently. That's just a fact, and there's is nothing wrong with that. Why do people argue it? If anything, I think its a compliment to those who choose to use them, and use them well.
