I own a lot of basses and almost always start a gig with a Stingray, Benavente, Gibson, Roscoe, Sadowsky, etc.... or whatever my latest GAS inspired acquisition is. At some point during the 3rd or 4th set, I always pull out one of my trusty Fender MIA P basses (my 1974 or 2008, doesn't matter) to down tune to C for one song we play.... and after the song... I almost ALWAYS tune the P to 440 and finish off the gig with it. IMO every gigging and recording bassist should own a P bass (G&L, Sadowsky, Avella Coppola, etc. with a split coil P P/U works too). I love Jazz basses and many others, but a P is just a great bass to own IMO.
