EMG Geezer Butler PJ Pickup Set (includes solderless install system for easy install) EMG Pickups along with legendary artist Geezer Butler have collaborated to develop the GZR-P and GZR-PJ signature bass sets. The Rock and Roll Hall of Fame bass player started working with EMG founder Rob Turner in 2011 looking to find the classic bass tone he had in Black Sabbaths early days. As Geezer and Black Sabbath moved from studio to touring in 2013 the final component of getting the classic Geezer tone was in play, the rigors of a world tour. To recapture Geezers early Black Sabbath tone, it meant a new EMG vintage style passive P & PJ design with a few modern touches. The all solderless P set uses Alnico 5 pole pieces and custom wound coils for just the right amount of punch and grit. The J (PJ set) also uses Alnico 5 poles and features two custom wound split-coils that both eliminate the noise and hum usually associated with early 70s bass pickups and allow for more power and volume than any other standard single coil J giving this set remarkable balance between the P & J. The result is unmistakable early Geezer Butler bass tone with deep, tight low end that you can hear on Iron Man, War Pigs, and Paranoid just like 1970s. Said Geezer, I never felt comfortable giving my name to any other pickups, but this time these have blown me away.
