hi people
im going to by a set of emgs extended pickup series :a40j and a 40p5 to put on a peavy grind ntb five strings bass .the spacing between the strings is a little closer than the standard spacing is it a problem ?
No problem. The EMGs have bar magnets, not pole pieces, so they'll pick up evenly over the entire width of the pickup.
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 the bar allows for any string spacing. Perfect for any multi stringed instrument, and the less conventional instrument.
Most EMG Pickups use a magnetic bar. Single coil pickups are available in both bar and pole-piece designs. There are fewer negative attributes to the bar and it's preferable, but if you like pole-pieces for your playing style then there is an EMG model for you.
