Effect name: Purple Cobra

Effect description:  Do not taunt the purple cobra.  This is a tightly compressed
distortion that runs through a fuzz destructor to create tight notes with lots
of colorful harmonics.  This effect also uses a pitch shifter.  Stepping on the 
right footswitch mixes in the lower octave

Left pot label: Tone
Left pot function: Tone of distortion

Center pot label: Drive
Center pot function: Amount of input drive going into destructor

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

Left footswitch label: Octave down
Left footswitch function: While pressed, mixes in a dropped octave

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