One standard feature on many models of solid state amplifiers is that of multiple channels. Most will feature two channels. In the game of amps, you get what you pay for, so a more expensive amplifier will usually have more features per channel.

On the amp we use in this lesson, the first channel is a basic clean sound with the minimum equalization settings needed (low, high). This is the channel generally used by most players using solid state technology. These players usually use effects pedals and rack units to supplement this channel. This is effective as a setup when the shape of your tone is controlled outside the amp with pedals and rack units.

The second channel's big difference is the gain feature. This allows an overdrive or distortion (the most used effect) to be added to your tone with the click of a button or the click of a foot switch. This works really well when going to a solo or lead line. You can also use it as a second clean channel but push the volume a bit to get that extra push when you need it.
