What differences could I expect to hear

[m chops]

If I swapped Phat cats for the hums ('59s I think) in my Korina Vector?

Thanks.

just did this in reverse , I would think a stronger high mid , more point to the note , stronger attack , should sound great in a resonant short scale, the cats sounded good in the Monaco , but it was a little too snappy w/ the long scale and cats, I prefered them in the short scale Newport

Since you're planning a swap, you might as well go for something more "upscale".... Fralin, Lollar, Haeussel, VooDoo....

You should be getting a meatier tone and increased output.

More violin-like sustain in the neck position.

At the end of the day it's still gonna be a great guitar, just better...
