From Way Huge;

The Swollen Pickle Jumbo Fuzz MkIIS serves up the same burly high
gain fuzz as the full-sized MkII but in a more petite package. With a
twist of the Sustain control, you're taken from mild crunch to
Armageddon! The Filter control retains its trademark insane range of
heavily bandpass-filtered tones, distinguished by remarkable girth and
sizzle, and the Loudness puts out enough volume to clobber any amp! The
Scoop tone stack control elicits classic Swollen Pickle mid-scoop or a
flat mid-frequency sweep, and the Crunch knob adjusts the compression
intensity of the fuzz. Finally, under the hood, the MkIIS has two
internal mini controls: Voice sets the intensity of the external scoop
control from light to heavy mid cut, and Clip varies between two sets of
clipping diodes for smooth or opened fuzz sustain.
