SCR-1 Created by popular demand from players, Cool Rails™ use the same twin coil design as our 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.
