Changing Tubes on Vacuum Tube Amplifiers

Summary: An amplifier is a natural or artificial device that is used to make audio or any type of signal stronger as it passes through the device. There are many different types of amplifiers. Some, like acoustic guitars and cellos, are acoustic or natural amplifiers. Other amplifiers that use electricity such as electric guitars and PA systems are electric or artificial amplifiers. Although you have much more control over tone and volume with an artificial amplifier, the quality of sound of a natural amplifier is usually preferred by musicians.
