Universal Audio UAFX Astra Modulation Pedal

Astra Modulation Machine

A Trio of Timeless Modulation Effects

Astra Modulation Machine is a complete sonic workstation. From spacey studio flanger tones of the 1970’s, to gritty bucket-brigade chorus, and luscious opto tube tremolo, Astra puts three perfectly-emulated modulation sounds at your feet. Chorus Brigade, Flanger DBLR, and Trem 65 settings — with secondary modes for Vibrato, Doubling, and more — combine for an abundance of tasteful tweaking.

 

Three egendary modulation effects:

 

Chorus Brigade

Based on the classic CE-1, the Chorus Brigade tone emulates every inch of this legendary pedal, expertly capturing its legendary bucket-brigade circuit.

Flanger/DBLR

Perfectly emulates the prized MXR studio flanger’s colorful, almost lo-fi-sounding "bucket-brigade" circuit — offering subtle thickening to whacked-out sci-fi effects.

Trem 65

Captures the balanced, warm tones of classic Fender blackface opto tube tremolo (called "Vibrato" on the amp).

 

Bonus X90 Phaser & Dharma Trem 61 effects
Based on the classic MXR "script" and "block" Phase 90 effects, plus a unique "Dharma" Dynamic Harmonic Tremolo tone — available free at pedal registration.
