The Book is still being written about what an 8-string pickup should sound like. DiMarzio think it should have a wide frequency response, be very articulate and dynamic, and not be muddy. The DiMarzio DP819 D-Activator 8-String Neck Humbucker is open, clear and very responsive. It maintains its sound character even with massive amounts of gain, it stays bright and articulate with lean amp settings. The D-Activator 8 coils are tuned to different frequencies, and combining this feature with a medium output level producers a clear, musical sound throughout the entire 8-string frequency range. Powerful and open sound Lots of headroom Excellent harmonics Responds perfectly to pick attack No muddiness on low strings Comes with wiring instructions
