Solderless setup with all required wiring available here.
The Mini Range series of P90s are P90s utilising FeCrCo screw magnets, similar to Wide Range humbuckers from Telecaster customs. This gives the pickups a brighter, more aggressive note attack, giving the pickups a tonality similar to a Fender style single coil. Below is the standard pickup set description. Due to using these screws, any mention of magnets in the description below does not apply, but is there for reference to the standard set.
The P90 sized adaption of the Desert Dew humbucker sized P90s
This pickup is beautiful clean. It has a thick, smooth treble response, and a brighter-than-humbucker bass response, giving it the ability to mix all the frequencies of chords in such a way that no single string rings out above the others. Flat response and crystalline clarity simultaneously seems like it would be impossible; but this melds the two qualities. The flat response can be excellent in high gain applications for adding natural compression so that the tone needs very little work after recording. The definition makes this pickup even excel at high gain rhythm, which can't be said about many neck pickups.
