A word from the manufacturer:

The ultimate chorus and modulation effects pedal. ModFactor utilizes two LFOs create rich expressive modulation effects—with one LFO modulating the effect while a second LFO modulates the modulation. All the standards - Chorus, Flanger, Phaser as well as Rotary, Tremolo, and Vibrato are included. Also features is the unique Undulator effect from the H8000 and a RingMod that lands somewhere between ring modulation and synthesis. The dedicated SLOW/FAST footswitch for ramping the LFO rate comes in handy. LFO rates can also sync to Tap Tempo and MIDI clock.

With 10 powerful algorithms to modulate your sound, the only problem is how to explain the magic coming out of that tiny little box.
