The result of years of research to come up with the right sound for a very demanding player"Steve Vai. Designed for maximum impact and power. The sound is tight, aggressive and loud. The DiMarzio DP159 Evolution Bridge Pickup is a hefty humbucker designed for maximum impact and power. The Evolution pickups sound is tight, aggressive, and loud. The DP159 Evolution incorporates DiMarzios patented dual-resonance coil configuration that senses more harmonic overtones than ordinary humbuckers. Perfect for solos that really cut through. Low notes are very tight, and the highs have a lot of presence. DiMarzio designed the DP159 pickup for Steves Ibanez Jems, but it can add a lot of punch and definition to Les Paul 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.
