The Universal Audio Astra Modulation Machine is a versatile modulation pedal with three main modes: Chorus Brigade (inspired by the CE-1), Flanger DBLR (recreating tones from rare rack units), and Trem 65 (based on vintage American amp tremolos). It offers stereo ins and outs, a USB C input for updates, and a Bluetooth app for deeper settings. This pedal captures classic modulation effects and is built for lasting use.
