Heres something I just wrote in a different thread, copying/pasting to save time:
"The single pickup Classic P-Bass voicing is one of the most popular recognizeable voicings in contemporary music, but its not like the StingRay MM Sound where actual physical equipment ( a Parralel wired MM as well as the proprietary nature of the Ray's PreAmp System) is coupled with pickup placement to achieve that voice. The P-Bass voicing is much simpler: A humbucking Pickup in the Mid Position -- thats it. Even a single-coil in that position will mimic the earliest P-Basses (such as soloing the mid PU on a Jazz -- it will be thin, but the voice is there). There are literally TONS of basses out there that have the P-Bass voicing (or variation of) as an option (such as G&L L-1000s, Peavey T-45s, etc) and can be further accented by passive or active electronics, EQ-shaping, techniques/playing style, to make up for the different tonal variances from type to type. Furthermore, there are many twin-pickup basses out there can have their mid pickups soloed to achieve that sound, like almost any P/J or G&Ls ( click the link in my Sig and scroll down to the last song "Old Skool Town" -- Hear that P-Bass? Its not: Its my G&L ASAT with mid pickup soloed in Series Mode).......So if your criteria is that "sound", understand that sound can be achieved on a LOT of basses that dont necessarily say "Fender Precision" on them, nor look like them, or play like them.....Now, if you want a P-Bass because you like the way it looks, like the way it plays, you want that P-Bass "mojo", or just so you can post pics on TB to get other P-Bass lovers to "Gawk" at your new bass, those are all legitimate reasons to get one because it boils down to just making yourself happy....but get out of this mindset and stop listening to all this "A P-Bass is all you need" garbage because that mantra will vary from the needs/wants of each individual player so Im gonna' call BS as I see it....... $.02, YMMV"
