If you like how it plays, have a well known pickup maker wind you something based around your thoughts or around the sound you imagine when you think of a Casino. All of a sudden there was all the brilliance I wanted to hear in that guitar.
I had a Casino and put in some cheap Kent Armstrong pickups in my run of the mill model, I still hated the way it played but it sounded good. I guess you know what you have, or what it sounds like you have. P90s can be anything you want them to be, they can be bright and chiming, and they can be dark and 'bluesy'.
