An EMG measures the electrical activity within the muscle by use of a sterile needle electrode, and there are many characteristics that an electromyographer can look at when evaluating an EMG. The activity within the muscle is recorded by the EMG machine and represented graphically on an electromyogram. This electromyogram measures the electrical activity of motor unit potentials within the muscles and represents them graphically on an X-Y axis. The X axis of the electromyogram represents time measured in milliseconds, and the Y axis of the electromyogram represents the amplitude of the motor unit measured in voltage. Because these electrical responses are represented in waves, those waves can be converted to sounds and listened to by the electromyographer. The examiner observing this activity can then make interpretations of the activity while watching and listening to the electromyogram. Often this begins with listening to the activity of the muscle with the needle moving in the muscle (called insertional activity), listening and observing to the activity of the muscle while it is at rest, listening and observing the motor unit morphology and recruitment patterns of the muscle with gentle contraction, and finally listening and observing the interference pattern of the muscle when it is at full contraction.

What are some good death metal styled pickups for bass guitar?
nothing wrong with EMGs , if not I loved rockfields like on disturbeds signature trayben bass through a microcube amp in my friends store it blew me away.
Can you put active pickups in ESP LTD KH-202?
The KH-602 has active pickups but the KH-202 has passive pickups. It is possible to convert to active - either EMGs or Seymour Duncan but you would have to find somewhere to put the batteries.
