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