X SERIES 7-String 707X Active Pickup, Black. The 707 has been leading the pack of 7-string guitar pickups since its debut in 2001. Before this model was introduced, existing 7-string pickups sounded muddy and dull on the low B string, especially when trying to hit artificial and natural harmonics, but the 707 eliminated all those problems. Featuring Alnico V loaded wide aperture coils we were able to beef up that Low B tone and at the same time provide a more responsive super tight overall sound. Whether you are ringing out Opeth-style jazzy chords or playing palm muted death chugs, even with the amp set to "kill", these pickups will articulate every note, harmonic and squeal you ask of them. Used equally in bridge and neck positions, these pickups will forever change how you hear and play your 7-string. The X series provide increased headroom giving the voicing an organic and open tone while still maintaining the clarity and response that EMG's are renowned for. X's are best described as bridging the gap between passive and active tone. Package Includes: EMG's exclusive Solderless Install System; split shaft volume/tone control set, output jack, battery clip set, screws & springs.
