If there are P93 pickups, thats not the common P90 vs humbucker sized P90.
By definition from Gibson - the P94 is a single coil similar to a P90 but in a humbucker sized package.
A P90 is slightly longer and narrower than a Humbucker; they wont fit in the same pickup route / cutout in the guitar.
A dog ear P90 is surface mounted and not easily adjustable for height; it has little brackets on the ends but can be shimmed.
A soapbar P90 is just the rectangular pickup and cover with screws that pass through it (small holes between A -D and G-B strings) allowing for easy height adjustment.

You want a good "P90 sound" sample?
The Who, Live at Leeds is considered a choice specimen.
Love that record.
I dig P90s too, (and single coils and humbuckers, others too).
