Designed to impart a classic and much-lauded tone upon your electric guitar, the JVM410C from Marshall Amplification is a four channel 2x12" combo amplifier featuring 100W RMS of power. The four channels are separated into Clean, Crunch, OD1 (Overdrive 1), and OD2 (Overdrive 2). Furthermore, all of its channels boast three specific modes to boot, giving you a total of twelve different basic timbres to choose from at any one time. Each channel offers its own gain, bass, middle, treble, volume, and reverb level controls.
Within each channel, you can cycle through modes in one of two ways: with the mode buttons next to the gain nobs or with the provided footswitch. Either way, mode selection introduces different types of gain, allowing you to soar into a variety of Marshall tones, and then assign these tones to the footswitch in ways particular to your fancy. This results in four individual channels you can recall at will—quite a useful prospect for the gigging guitarist. Additionally, you can assign any channel to one of two separate master levels.
