Modulation pedal

The UAFX Astra Modulation Machine pedal combines three classic modulation effects: bucket-brigade chorus/vibrato, studio flanger/doubler and tube tremolo.

• Emulation of an iconic Japanese bucket-brigade chorus/vibrato pedal (circa 1976)
• Complete circuit capture of a legendary 1970s rackmount studio flanger/doubler
• Trem 65: model of the tube-driven optical tremolo of 1960s American guitar amps, with variable sine and square wave settings
• UAFX dual-engine processing with separate stereo instances of each effect
• Inputs and outputs for mono or stereo operation
• Live and Preset modes, silent switching, true or buffered bypass
• MIDI over USB for preset changes, BPM clock sync and realtime control of effect parameters (requires a compatible USB MIDI host)
• Control via the UAFX Control app over Bluetooth or USB cable
• Additional Phaser X90 and Dharma Trem '61 effects downloadable after registration
• Power: isolated 9 V DC supply with 400 mA, center negative, 2.1 x 5.5 mm barrel connector (sold separately)
