Developed by Master Luthier Jim DeCola and based on his groundbreaking pickup designs for legendary Kramer artists, the Kramer Eruption is a high-output humbucker pickup with all of the Made to Rock Hard tone and attitude you expect from Kramer. They feature Alnico 5 magnets, 4 wire 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.
