In 2006, we took a close look at the most popular active neck and bridge humbuckers to see if we could capture all of the good qualities and eliminate the disadvantages: cold sound, limited dynamics, running out of headroom when played hard, and the need for batteries. The end results are the D Activator™ Neck and Bridge. They use coils tuned to specific frequencies. The purpose is to shift the resonant points of the pickups to the fundamentals and harmonics that you want to accentuate from the guitar, and they respond instantly to hard or light pick attack. The sound is powerful, clean, and open, with excellent harmonic overtones and very tight lows. The best way to describe the D Activator™ Neck pickup is that it is big, bright, and open sounding with surprising string – to – string balance. The D Activator™ Bridge has an enriched harmonic quality and the notes want to sing.
