Three of History's Most Mind-Expanding Modulators, Perfectly Captured in a Stompbox.  
 
Engineered and developed by the acclaimed team at Universal Audio, the UAFX Astra Modulation Machine boasts powerful dual-processor architecture for the most sonically authentic classic Chorus, Vibrato, Flanger, and Tremolo effects ever available in a stompbox.
