Effect name: Compressor / Sustainer

Effect description:  This is an example that shows how to use the fx_compressor 
effect to create a compressor sustainer pedal

Left pot label: Threshold
Left pot function: The threshold where compression kicks in

Center pot label: Compression Rate
Center pot function: The amount to compress after threshold crossed

Right pot label: Gain
Right pot function: The output gain of the compressor

Left footswitch label: Bypass
Left footswitch function: Bypasses the effect

Right footswitch label: Nothing
Right footswitch function: Nothing
