The Eruption humbucker pickup is developed by master luthier Jim DeCola based on his groundbreaking pickup designs for legendary Kramer artists. The Kramer Eruption is a high-output humbucker pickup with all of the ready-to-rock tone and attitude you expect from Kramer. They feature Alnico V magnets, 4-conductor leads for coil splitting and short-leg baseplates to ensure easy direct replacement for most humbucker-routed guitars. They're also wax potted to remove all internal air space and any chance of microphonic feedback.
