| amplification |
The act of increasing the magnitude of a signal without altering any of its other qualities, or the use of a device (amplifier) that does this. Specifically important in the transition from acoustic blues, where amplification was rarely used in live performance, to electric blues, where performers began using amplifiers, particularly with guitars and harmonicas, to increase the volume and power of their performance. ...

| amplifier |
A device which takes in a weak electric signal and sends out a stronger one. Amplifiers are used to boost electrical signals in many electronic devices, including radios, televisions, and telephones. Both vacuum tubes and transistors can be amplifiers, though today vacuum tubes are rarely used for this purpose.
