So, I played a bunch of P basses unplugged in a store, and I don't know whether the unplugged sound translates well to the plugged-in sound, but I liked the sound of the one that I bought the most. And playing it plugged in, it still sounds really good. But it's a MIM. In general, how to MIM P basses compare to MIA P basses? I'm guessing that I might be able to benefit the tone a bit by upgrading some stuff, like the pickups, the bridge or just saddles, and the nut. If I change these things, will it be as good as a MIA P bass? Thinking of the truss rod, do MIM P bass necks have inferior stability to MIA ones? Will replacing the bridge or saddles do anything to improve the tone, and which should I replace it with for a linear step up? BTW, which pickups would be in an early 90's MIA P bass? I think I want to try those in this guitar. Thanks.
