SuperRiff is a developer of free VST instrument plugins, credited on plugin distribution sites as SuperRiff Inc. The project released two simple sample-based rompler instruments — SuperRiff Guitar and SuperRiff Bass — aimed at producers needing basic rhythm, lead, or bass parts inside a DAW. Both plugins target rock-style productions but are usable in any genre.

SuperRiff Guitar contains custom distorted electric guitar single-note samples spanning E1 to D5, with three velocity layers per note triggering different sample types (open string, palm-muted, and vibrated single notes). SuperRiff Bass offers a comparable set of bass guitar samples. Both include Volume, Pan, ADSR envelope controls, and a subtle flanger unit, and ship as Windows VST plugins distributed free of charge through sites such as KVR Audio and Plugins 4 Free.

Little public information exists about the people behind SuperRiff. The plugins are described by the developer as having been made for fun rather than as a commercial product, and the original superriff.com domain no longer hosts an active site.

SuperRiff has 1 product cataloged on Equipboard, including FX Bundle Plugins.
