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.

From spacey studio flanger tones of the 1970’s, to gritty bucket-brigade chorus and luscious opto tube tremolo, Astra Modulation Machine puts three iconic vintage effects at your feet, in a beautifully-crafted pedal that’s built to last decades.

Chorus Brigade: Classic ‘70s analog bucket brigade chorus with additional Vibrato mode.

Flanger/DBLR: Studio flanger/doubler tones modeling legendary rack effects units.
