So I'm trying to prepare my Christmas list, and I really like the sound of the SD Phat Cat. I was thinking of dropping it into a guitar that currently has humbuckers, and the SD site says that it can be put into an HB-equipped guitar.

Does anyone have one? Do any special mods have to be made to the electronics, being that it's a P-90 and all?

This is my first replacement pup buy, and I'll be going to a tech for the installation, of course, so I just wanted to know some basics about replacement.
im pretty sure its like every other passive pickp, its a p90 in a humbucker, so it shouldn't be any different installing it.
