This is the Arpanoid from Earthquaker Devices, a polyphonic pitch arpeggiator designed just for guitar players. With the Arpanoid , you can play one or multiple notes at once and transform them into ascending and descending scales. 8 Total modes provide different sequences in both major and minor keys and you have choice of including an octave below or above the input signal. Random modes in both scales produce unpredictable patterns that stay in tune with your music. Plus, Earthquaker Devices provides two independent mix controls allow you to blend in just a touch of this rhythmic effect or isolate the arpeggios to transform your guitar into a whole new instrument.
