Electromagnetic pickup output is described in a couple different ways, with the most common being in kilo-Ohms or "K" of resistance, although this isn't a measure of actual output, but rather, a shorthand commonly used in the pickup industry. The more accurate measure of output is in Henries of inductance. Both measurements are provided below..

Along with other factors, different output levels also effect the tone of a pickup. The higher the inductance, the warmer the tone becomes and the greater the volume. Lower inductance pickups of similar design tend to be brighter with lower volume. This is why a lower inductance pickup is often used in the neck position with a higher inductance pickup in the bridge position to balance things out. String vibration at the neck is greater and results in a warmer tone and greater volume and the converse is true for string vibration near the bridge.

3K (kiloohms) DC resistance

4K (kiloohms) DC resistance
.33H (Henry) inductance

5K (kiloohms) DC resistance
.52H (Henry) inductance
