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.
 
Using alnico 3 magnets, the Jazz ninety is especially suited to semi acoustics. Roll off that tone a little for a perfect jazz sound.
Mind you, this pickup is no slouch when it comes to rockier stuff, and takes pedals well. It’s low string pull maximises your guitar’s natural sustain.
