Do You Have a Trade In?


The Delta II is a powerful optical harmonic tremolo with extensive tone shaping and rhythmic capabilities. The novel LFO enables its pilot to craft harmonic, and traditional tremolo sounds that stagger, hop, buzz, beat, and swirl with unparalleled variety using a brilliantly simple interface. Soar through the sonic scenery as evolving rhythms throb and pulse through your consciousness like stars flickering across the cosmos.


Delta II Standard Edition colorways offer vivid visual appeal to match their breathtaking tonality and thoughtful functionality.


Smooth and lush all analog signal path, with 3 distinct voices

Harmonic or traditional tremolo with a twist of the LAG control

Wide-range LFO capable of slow pulsation to audio-rate madness
