The Seymour Duncan SHR-1 Hot Rail Stacked Single Coil Pickup is one of the highest output pickups made. It's a humbucker that fits into a normal single-coil pickup slot, so you get noise canceling without cutting a large hole in your guitar. The 2 thin blades with powerful coil windings give you the incredible sustain and fat, full sound that's needed for playing heavier rock music. This Seymour Duncan SHR-1 pickup responds to the subtlest finger movements.
