Universal Audio UAFX Astra Modulation Stereo Effects Pedal

Universal Audio Astra Modulation Pedal Overview

Universal Audio makes some of the best studio outboard equipment and digital processing around—and now, the company extends its tech to stompboxes with the Universal Audio Astra Modulation Pedal, a modulation pedal for electric guitars, basses, and similarly amplified instruments. Sporting a stereo I/O path, the pedal combines UA digital know-how with analog craftsmanship to deliver guitar players three stellar-sounding modulation effects.

Classic chorusing, flanging, vibrato, and tremolo effects are all accessible in the pedal itself. Other effects can be downloaded from Universal Audio and loaded into the pedal over USB. In addition to silent switching and true/buffered bypass selection, the pedal offers a bevy of control as well as instant save/recall of your favorite sounds as presets.

(Note: The required power adapter is available separately.)

3 Timeless Modulation Effects

• The pedal offers three classic modulation effects, including:
• Chorus Brigade: A classic ’70s analog bucket-brigade chorus with additional Vibrato mode.
• Flanger/DBLR: A studio flanger/doubler with tones modeling legendary rack effect units.
• Trem 65: An opto-tube tremolo derived from iconic blackface amps of the mid-1960s.
• In addition to these three effects, you’ll have access to more from the Universal Audio website, including the Phaser X90 and the Dharma Trem 61.

Powered by Dual-Processor UAFX Engine

• This dual-processor enables you to achieve a powerful and authentic sound and also facilitates simple preset loading with instant recall. Each effect allows you to take advantage of secondary controls to shape the modulation.

Classic UA Analog Design

Just like classic and modern UA gear, this pedal is built to last. It also offers both true and buffered bypassing (thanks to a UAD firmware update), as well as silent switching onstage and in the studio.
