The Floor Board has two main modes of operation: Channel Select and Effect On/Off. Effect On/Off gives you instant direct access to your Digital Guitar Amplifier System's effects. Step on one of the sturdy steel Effect On/Off switches and the amp instantly responds by turning that effect on or off, just like a classic effect stomp box. Red lights above each Effect On/Off switch show you whether an individual effect is On (light on) or Off (light off) so you can see the details of your Channel's setup at a glance.
