Each Duncan Distortion in this set uses a massive ceramic magnet together with a pair of over-wound coils for the ultimate heavy guitar sound. This matched pair lets you go from chunky, low-end, power chords to raging leads with aggressive harmonics. Perfect for drop-tunings. Both position-calibrated pickups include four-conductor wiring for trick switching options. Recommended for heavy rock, punk, and metal. Wiring diagram and mounting hardware included.
