Created due to popular demand from players, Cool Rails use the same twin-coil design as Duncan's Hot Rails, but are wound to produce a clear, bright, 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 loud, punchy single coil sound for stage work. Cool Rails are great on their own and also make an excellent match on a guitar with a hot humbucker in the bridge position. Specify black or white, neck or bridge. 4-conductor cable.
