Effect name: Warm Distortion 

Effect description:  This is an example that shows how to use the fx_destructor
effect to create a smooth, tube-like distortion sound. To make this more interesting,
try adding additional destructor and tone (fx_biquad_filter) elements either in series
or in parallel.

Left pot label: Drive
Left pot function: Sets input drive of distortion

Center pot label: Tone
Center pot function: Sets tone of distortion

Right pot label: Gain
Right pot function: Sets output gain of distortion

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

Right footswitch label: Drive boost
Right footswitch function: Sets drive to max while held down
