to the OP:
- good setup. Some things simply are mandatory and objective. for example the neck relief, the bridge saddle height (action). You can achieve custom settings even for this parameters but you can even stuck with the suggested ones, as your starting point at least.
. pickup height: massive influence on the pickup sound. There is usually a sweet spot, not too low and not too high, where you find that colour that makes your heart pump.
usually I find a precise sweet spot, and the tonal feature disappears if I turn those height screws up or down by 1/4 of a turn, so it is a delicate process, and requires good hearing, good headphones and a lot of patience
- strings: wow...search on TB, nickel or steel, rounds or flat, you can fine tune your bass. even string type and brand has a huge impact on tone
- technique: in my personal opinion a P-bass sounds its best hitting the strings just above the pickup, but I know others that do differently.
After having done these points, look at your amp
