Chorus Brigade
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 Trem 65

Captures the balanced, warm tones of classic Fender blackface opto tube tremolo (called “Vibrato” on the amp) Bonus X90 Phaser & Dharma Trem 61 effects
Based on the classic MXR “script” and “block” Phase 90 effects
