Guitar Amplifier Storing Your Own Presets: Each channel of the RFX65 has two factory assigned DSP presets, as shown on pages 10 and 11. No matter what the settings of the DSP controls, the preset is recalled when a channel is selected. You may change the DSP settings by rotating the DSP con- trols - these changes will remain active until a different channel is selected, but will not be there for later use unless they are saved. To save a new DSP preset to a channel, first make the desired DSP ch

Guitar Amplifier Using the Footswitch for More Presets: The Crate three-button footswitch supplied with the RFX65 allows access to an addi- tional DSP preset for each channel of the amplifier.

These are referred to as “DSP Bank ‘A’.” When the #3 button is switched and the LED is out, a second DSP preset may be stored and recalled for
