Each of these four channels features three voicing modes, giving you twelve preset sounds in total. Each mode consists of a different level of distortion. The built-in digital reverb of the JVM410C has a level control for each channel, so that you can have varying degrees of saturation, and be able to switch from one level to another (with the included six-button footswitch). There are two effects loops and two MIDI sockets on this head as well, so that you will be easily able to use complex effects systems with this head. The JVM410C has a Vintage speaker and a Heritage speaker, which is what differentiates it from the lower cost JVM410H (which is a speakerless head version). The Marshall JVM410C comes in the classic black color.
