"Hi. I'm Rick Tobey and I'm going to talk about how guitar amplifiers work. Now basically a guitar amplifier amplifies the sound of an electric guitar. And most electric guitars, when they're not plugged in especially if it's a solid body guitar like this one you can barely hear it. Of course when you plug it into an amplifier and turn it on it amplifies the sound. Now this amplifier is a 1980's Fender twin reverb. It has two 12 inch speakers and 100 watts and it has two channels. This is a clean channel which gives you a volume, treble, mid range and bass control. And then it has a second channel which give you the added control of gain and also presence so you can kind of get a distorted sound. So this is how it sounds through the clean channel and then if you switch to the other channel that has the gain control and you turn the gain up and the volume down to control the loudness. You see how you can change the tone to get a good kind of a distorted sound. And that's how a guitar amplifier works."
