Chorus Brigade emulates a classic 1976 Japanese chorus and vibrato pedal, including the preamp coloration of the original. Flanger Dblr captures a late-'70s rackmount bucket brigade flanger and doubler. Trem 65 recreates the optical tube tremolo of '60s American amplifiers.

Speed, Depth and Intensity set the core movement, while Shade, Shape and Mode adjust each effect's character. Separate engines run each effect in stereo, so the pedal can spread modulation across two amps or channels.

Live mode follows the knobs, while Preset mode recalls a stored sound from the second footswitch. The UAFX Control app adds editing over Bluetooth or USB, and USB MIDI handles preset changes and clock sync. Two extra effects are downloadable after registration.
