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 Neck model has both power and clarity the low B string stays solid and doesnt sound like mud with extreme overdrive, and the high strings sing all the way up the neck. And it doesnt need batteries.
