Thunderbird pup

[Freuds_Cat]

OK I am a novice with the whole Gibson pickup thing. Can any one explain what this is about?
It looks like a split  P bass pup under a T-bird cover.

That is an "early" post '88 production pickup quite different than the present ones.........Thanks for bringing it to my attention, I'll likely bid on it!

feel free Mark.  What difference in sound did these make?

Hard to explain, but I like them a little better than the contemporary one. The treble side is a bit better but not harsh.
