Created by popular demand, Cool Rails use the same twin coil design as our Hot Rails, but are wound to produce a clearer, brighter, and more dynamic sound. Hotter and louder than both the Vintage Staggered (SSL-1) Hot Stack (STK-S2) pickups, Cool Rails are for players who need a louder, punchier, and fatter single-coil sound. Comes with four-conductor hookup cable.
