You're mistake is in the "they can do that with Strats" part.
I say, no they can't. A really good large number of folks tend to agree with that as well.
I do know the P100 from Gibson is totally different from a P90. Then again, P90's are different from each other.
THERE IS NO ONE SINGLE P90 TONE, just as there is no single HB tone. Even the Gibson P90, which has officially been offered one way - as the P90, take it or leave it - has run hot and cold over the years, on purpose, to suit the models Gibson was producing at any one given time.
For sure, a 7k P90 and a 14k P90, both original from Gibby, sound totally different.
