Humbucker sized ‘P90’ single coil:
Though they are one of the oldest pickup designs around, P90s never seem to lose their appeal. However, it’s only in fairly recent years that the tone of a proper ‘90’ has been available in humbucker size.  
In the early days pickup winders fudged about using humbucker bobbins inside P90 style casings, or cut down P90 bobbins to fit ‘bucker’ sized covers.
 
Just like the Mighty Ninety but using alnico 2 magnet in the neck, and alnico 4 in the bridge for a smoother blues rock tone. Buttery, singing leads are the order of the day here.
