I respect that and if you need a B string and/or authentic urb tone, then I support your point.I'm as big a fan of the P bass as there is(I own 4 or 5 of them), but have to disagree with you there... In order to properly cover many of today's country songs, one needs a 5 string - and one of the main reasons why I get the call for the acoustic quartet is because I can bring and play a good quality AEB... Think what you may, but depending on the quality($$$) of those gigs - you'd be wrong...
I'm only saying, I can't think of a single electric bass other than the P that can approach and/or satisfy these gigs. Perhaps a P5 would get you even closer.
