From the engineering side, any time I had something other than a P bass, or maybe a good Jazz, I had to do all manner of equalization, dynamics (normal and multi-band), automation and what not to bring some consistency into the part. Still had to battle disappearing bass syndrome. Never happens with the P bass. Just a touch of compression and you are good to go.
Im not understanding this: Youre saying that if three bass players that play P-basses come in
1) Player 1 - Very Consistent Fingers w Light touch/finesse - very even note delivery, tapewounds, fingers over pickup (very legato player) '72 Precision w Stock Pickup (passive), low pickup height, Jazz RnB session
2) Player 2 - Ham Handed Heavy Pick and Slap, note delivery sporadic with lots of transients and artifacts, Brand New Roundwounds, EMG P pickup (active), high pickup height, aggressive Metal
3) Player 3 - Semi-Consistent Fingers/slap w Medium touch - fairly consistent note devivery but slap style is slightly more aggressive with some transients and artifacts, Brite Flats strings, Seymour Duncan Quarter Pounder (passive Hi Output), high pickup height, Project will incorporate tuned 808 as sub-bass reinforcement, fingers toward bridge (very staccato player), Electro Funk
..that all you would need is a touch of compression for each?
It seems to me that you would have to do the same amount of tweak work as you would with a player using any bass.....The biggest factor is the delivery consistentency of the individual player, not how consistent the bass-type is that comes through the door....ymmv and all dat
