Gamechanger Audio AUTO Series Chorus Pedal

The AUTO CHORUS encapsulates three rich and warm-sounding types of modulation effects: chorus, ensemble and flanger.

CHORUS algorithm is a classic simple chorus effect that mixes the dry sound with a delayed and pitch-shifted signal. For a pure vibrato effect, set the LEVEL KNOB MODE to MIX, set the LEVEL knob completely clockwise, and set the FEEDBACK knob completely counter-clockwise.

ENSEMBLE algorithm is a more lush version of the chorus. This algorithm mixes the dry signal with three slightly offset and pitch-shifted signals. This ensures that in the higher DEPTH setting, the internal modulation rate remains less audible than in the CHORUS algorithm.

FLANGE algorithm shortens the delay of the chorus effect to achieve the typical jet-engine-like effect.

RATE adjusts the modulation range from 0 Hz to 819.16 Hz. When turned completely counter-clockwise, the pedal stops modulating the delay line and the effect is stuck on a static delay time controlled by the DEPTH knob. When the RATE is set to 0, the DEPTH knob allows you to dial in various comb-filtering sounds.

DEPTH control. The minimum counterclockwise setting is no modulation depth, which means that the wet signal has a constant short delay (since CHORUS and FLANGER are delay-based effects). This means that even if the modulation depth is zero, you can still use the FEEDBACK control to shape the wet sound.

FEEDBACK level adjustment. High settings introduce a metallic resonant character that is dependent on the selected algorithm. The maximum setting pushes the effect into an infinite feedback loop.
