This set includes the DiMarzio DP719 D Activator 7 neck pickup and the DP720 D Activator 7 bridge pickup for 7-string guitars.
Active humbuckers have a distinctive sound: powerful, clean, open-sounding, with excellent harmonic overtones and very tight lows. This also fits the description of a great 7-string pickup, if the problems associated with active pickups — sterile sound and limited headroom — could be eliminated. The D Activator 7™ models do just that.
The DP719 D Activator 7 Neck model has both power and clarity — the low “B” string stays solid and doesn’t sound like mud with extreme overdrive, and the high strings sing all the way up the neck. And it doesn’t need batteries.
The DP720 D Activator 7 Bridge has the same loud yet clean sound as the best active humbuckers, and killer harmonics. The low "B" string is all about attack, not mud. It responds instantly to hard or light picking. In a word: it rocks. No batteries required.
