All that said, I still think the engineers will be happier if you just show up with a P bass.
If you've just time travelled to the 1950's or 1960's, that's certainly true. I don't think Engineers nowadays are that limited in their thinking - I've worked with a lot of different engineers (including myself), and I've never run across one with that mindset. I've never been asked to play a P bass, or indeed any bass with flats. That legend is from a time when there was no EQ on the recording console, the studio had one kind of mic or 1 DI to use for bass, and they were doing a LOT of sessions in a day. None of that applies today.
However.....
If you're doing Motown-esque stuff, then a P bass with flats is certainly a very good suggestion - not because the engineers want you to, but because that is the gear that Motown was played on.
