Chorus Brigade Resurrects a Classic

The Chorus Brigade effect meticulously recreates the famed analog chorus and vibrato unit from the 1970s. With controls for speed, depth, level and mode, you can dial in every nuance of this influential sound, from subtle shimmer to seasick sway. The Chorus Brigade's circuitry gives a dimensional, retro character that stands apart from sterile digital replicas.

Flanger/DBLR Bends Time and Space

The Flanger/DBLR effect captures analog sound in exacting detail, simulating its colorful, somewhat lo-fi bucket-brigade circuit. Tweak the speed, depth and intensity knobs to conjure anything from a subtle thickening effect to an otherworldly whoosh.

Trem 65 Delivers Opto Tremolo Warmth

Based on the beloved tremolo circuit in the American '60s amplifiers, the Trem 65 effect faithfully recreates their balanced, warm pulsations. Choose between sine or square wave modulation, and adjust the intensity and speed for tremolo that moves from barely perceptible to intensely pulsing. The Trem 65 gives single notes and chords alike a pleasing undulation that evokes vintage rock and roll.
