So around the time of the rolling rock festival, I see that Dean Deleo has humbuckers in his guitar, and I thought p90s were single coil. I know that they make them humbucker size now (p94t). What kind of pickups are those? I really want some p90s but i doubt they will fit in the cavity of a humbucker.. I have a Les Paul Studio. And I read on some sites that he has P90s in his Les Paul??? Whats the difference in sound between the p90 and p94t, there has to be some sort of difference. Any real information pertaining to my questions would be appreciated!!
