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.
