EMG-ZW Zakk Wylde 81 85 Humbucker Pickup Set Easy Installation: EMG´s are easy to install. Each pickup features EMG´s own Quik-Connect header and mating cable for quick installation. Included with each pickup are pre-wired volume and tone controls, battery clip, output jack, and diagrams. This model is designed for direct replacement into most standard instruments. There are instances where "direct" replacement isn´t possible, but a minimum of work should be required. Construction: There is no other pickup built as well as an EMG. The coils are precision wound, matched both resistively and inductively, and finally, vacuum sealed. The internal preamplifiers are Surface Mount Technology (SMT) for quality and reliability. The pickups are tested for audio quality and reliability before encapsulation and again before shipment. String Interface: The first choice in design is the string interface. The selection of a bar magnet or individual pole pieces is also an important one. All initial EMG designs use a bar magnet for two reasons - Pole pieces place too much magnetism under the strings and cause the lower ones (primarily low E, A, and D) to go "out of pitch" with a Doppler effect. This is especially true of the Fender Stratocaster* where 3 poles under each of the strings push and pull them through a variety of unnatural movements. Poles can also make intonation and tuning difficult. On the other hand, pole pieces have the benefit of a percussive attack giving the pickup much more of a "plucky" sound. Designs featuring a bar magnet have a much more linear (balanced) output from string to string. Its attack is less pronounced than the pole piece design resulting in smoother distortion, and much better sustain. String bending is smoother because the output doesn´t fade when you bend strings. By relying on the internal preamp for gain the bar magnet can also be smaller, further limiting the magnetic "pull" on the strings. And, the continuous magnetic field of
