This is a single-coil pickup set, likely from the early days of Japanese-made guitars, judging by the construction. The pickups with an "❌" sticker on the back are defective (open circuit) and will be included as a bonus. Magnets: Alnico rod Pole piece pitch: All 49mm Magnetic polarity: All S-top Resistance values are written on the back. No potting appears to have been done. No screws, covers, or other accessories are included. Please purchase only if you understand that this is a used item.
