These are your quick ticket to getting P90-like tones from a guitar designed for humbuckers. Designed as a drop in fit for any humbucker, these humbucker sized P90s are true single coils that can be dropped in for a significant tonal upgrade. These pickups are made with alnico 5. This gives them a more scooped tone, with lots of highs and a thick, tight bass. P90s compared to humbuckers are brighter, clearer and more articulate. Due to their single coil design, they have a much smaller string sensing window. This means the range of harmonics they pick up simultaneously is smaller, making their tone much like a halfway between a single coil and a humbucker tone. White wire is neck, black is bridge. Specifications (neck and bridge) - Resistance: 8k Magnets: dual alnico 5 Spacing: 50/52mm Output lead - single conductor + shield Supplied with mounting screws and springs.
