DiMarzio DP820BK

D Activator 8™ Bridge DP820BK. The book is still being written about what an 8-string pickup should sound like. We think it should have a wide frequency response, be very articulate and dynamic, and not be muddy. This is the basic D Activator™ bridge sound. The low notes are big and percussive, and the highs have a lot of cut without being piercing. Recommended For Bridge position. Tech Talk The D Activator™ 8 bridge model is most definitely a high-output pickup. The two coils are tuned to different frequencies for powerful, focused bass response combined with warm highs and extended harmonic overtones. The lows are just as tight and defined as the D Activator™ 6 and 7-string models, and the highs are a little smoother. NOTE: If you are replacing active (battery powered) pickups in your guitar, we strongly recommend replacing the controls with 500K potentiometers. 250K is the minimum recommended control value for use with this model.
