This thread really does crack me up. I'm guessing most self respecting music lovers, let alone musicians wouldn't be in the slightest interested in what MOR sludge the average studio may wish to make to be played as Muzak in a local elevator. I'm surprised they care that much what bass guitar is used so long as it's generic enough sounding (I seem to remember my K Catalogue Bass recorded adequately for a generic bass sound).
I would wager 90% of Talkbass users aren't terribly interested in this stuff but may be either hobbyist musicians or musicians in bands. I suspect also that similarly low proportions of new bass guitars are sold to sessions musicians - in fact even fewer because I recall conversations with Nashville guys who referred to these people favouring the 'vintage' instruments for their sound (even though allegedly you probably can't tell once they're on whatever track or elevator soundtrack).
I can only presume people are trying to persuade us to buy Precision basses by association with a desire to make elevator music or some other form of consumable music where the player's sound is relatively immaterial, provided its generic.
Come on guys, what happened to music as art? Are we really saying the highest pinnacle we're seeking is elevator music - well I'm certainly not!!! (Although I might consider playing my SR5 on some if anyone asks - for a laugh if you see what I mean!! I understand they're quite popular in Nashville).
