Passive vs Active pickups. One last major factor involved is the operation means of the pickups. Pickups will either be passive or active. There are also more complicated ways of pickups operating but these are often very high tech ways that will carry very unique properties. Most pickups are passive. Passive pickups require that the guitar is plugged into an amplifier that is connected to a power supply, since the pickups themselves do not provide any means of pre-amplification to boost the signal they capture. Active pickups have a built-in power supply within the guitar, and most are powered by a 9 volt battery, or similar. This allows for more expansive control over the guitar tone when using the on-board controls (volume knob, tone controls, pickup selectors, etc.) although many say there is also a distinctive difference between the sounds of active and passive pickups which can be hard to resolve, even with other tonal controls.
