The Evolution® Neck and Bridge humbuckers are the result of two years of research to come up with the right sound for a very demanding player: Steve Vai and his Ibanez® Jems. Both pickups are designed for maximum impact and power. The neck pickup is fat, punchy and loud. The bridge pickup is tight, aggressive and louder. Both pickups have our patented dual-resonance configuration to reproduce more harmonic overtones than conventional humbuckers. Evolution® pickups are not polite-sounding, and they’re not for the inexperienced, but – if you’ve got the chops and a hot amp – your sound will burn. The Evolution® pickups were originally designed with live gigs in mind, but they have so much presence and definition that they’re great recording pickups, too; they slice right through even the densest mix. The Evolution® bridge pickup works best for soloing where the sound must cut through. Low notes are very tight, and the highs have a lot of presence, enabling the pickup to be heard in almost any situation. Obviously, the Evolution® was designed for Steve's Ibanez® Jems, but it can add a lot of punch and definition to Gibson® Les Pauls® and similar set-neck guitars - even the lowest bass notes really jump out of the amp, and feedback occurs easily with a wide range of harmonic overtones.
