Astra Modulation Machine

The Astra Modulation Machine by Universal Audio is a versatile stereo modulation pedal designed to deliver authentic vintage modulation effects. It features three main modulation modes, each with three variations, providing a wide range of sonic possibilities. The modes include:

1. Chorus Brigade: This mode emulates the iconic Japanese bucket-brigade chorus/vibrato from 1976, offering rich, luxuriant chorus and wavy vibrato effects.

2. Flanger DBLR: Replicates tones found on rare rack units, delivering thickening tones and adding movement to the sound.

3. Trem 65: Based on tube-driven optical tremolos found in vintage American amps, this mode provides authentic tremolo effects ranging from subtle shimmering ripples to choppy mayhem.

The Astra Modulation Machine is built upon the powerful UAFX dual-engine processing, allowing separate stereo instances of each modulation effect. It also features studio-grade conversion, Live/Preset modes, true/buffered bypass, and silent switching for seamless integration into any rig.

The pedal offers stereo inputs and outputs, USB-C input, and Bluetooth app connectivity for firmware updates and additional downloadable effects. The Astra Modulation Machine requires a modern 400 mA isolated power supply for operation.

Overall, the Astra Modulation Machine is designed to provide musicians with a wide array of vintage modulation effects, robust craftsmanship, and the potential for future updates, making it a valuable addition to any pedalboard.
