There are four channels, Clean, Crunch, OD1 and OD2, which when in manual mode operate like any normal amp. When in preset mode, whatever settings you dial-in can be stored, so that when you switch to that channel, those settings will be recalled.

The MG30CFX has a bigger sound than the MG15CFX with slightly lower frequency response, and is loaded with a 30 Watt, 10″ Custom speaker.
