UAFX 2.0 Firmware Update
Launching November 11, 2025, the UAFX 2.0 firmware update delivers a major performance upgrade to Universal Audio’s two-button pedals, unlocking deep MIDI integration, enhanced footswitch control and streamlined app connectivity. Players can now select from four new footswitch modes—Live/Preset AB, A/Bypass + B/Bypass (Tour Mode), A/B–C/D and Boost + Live/Preset—ideal for live "channel-switching" workflows. The update introduces 128 recallable presets via MIDI Program Change, real-time parameter control through MIDI CC messages and MIDI beat clock sync for time-based effects, including the Starlight Echo Station, Astra Modulation Machine, Galaxy ’74 Tape Echo & Reverb and Del-Verb Ambience Companion. Bluetooth connectivity has been rebuilt from the ground up for increased reliability, while a new wired USB connection enables direct app control from iOS or Android devices. USB MIDI support further enhances expression, preset switching and clock sync capabilities, making it easier than ever to integrate UAFX pedals into modern performance rigs. All updates are free and compatible exclusively with dual-footswitch UAFX models.
The flagship Astra Modulation Machine pedal establishes a new standard for faithful emulations of coveted analog effects, delivering a sonic authenticity that surpasses all other stompboxes. Featuring three legendary effects—the Chorus Brigade, Flanger/DBLR and Trem 65—it conjures the tones that shaped rock history. Operable in mono, dual mono and stereo modes, the Astra Modulation Machine lets you craft lush soundscapes in any configuration. With rugged construction, intuitive controls and preset capabilities, the Astra Modulation Machine gives you a portal to the past and a path to new discoveries.
Features
- Based on the classic CE-1, the Chorus Brigade tone emulates every inch of this legendary pedal, expertly capturing its legendary bucket-brigade circuit
- 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
- Captures the balanced, warm tones of classic Fender blackface opto tube tremolo (called "Vibrato" on the amp)
- Based on the classic MXR "script" and "block" Phase 90 effects, plus a unique "Dharma" Dynamic Harmonic Tremolo tone—available free at pedal registration
For three classic effects and loads of features. Order today.
