I took them out from Ibanez guitar after purchasing. Hardly used.

The 707 has been leading the pack of 7-string guitar pickups since its debut in 2001. The EMG 707 eliminated the problem of a muddy low B string that often lacked rich harmonic character and definition. Featuring Alnico V loaded, wide aperture coils, EMG was able to beef up the Low B string tone while maintaining a balanced and articulate upper register. This provided the responsive and tight sound seven string players grew to love. Whether you are ringing out Opeth-style jazz chords or playing palm muted death chugs, these pickups will articulate every note, chord, and harmonic you ask of them. Used equally in the bridge and neck positions, these pickups will forever change how you hear and play your 7-string guitar. Solderless wiring makes installing the 707 easy to do on your own.
