What is Chorus?
Chorus creates the illusion of multiple instruments playing the same part by mixing your dry signal with one or more delayed copies that are modulated in pitch and timing. This mimics the natural variations that occur when multiple musicians play together.
How It Works
Delays signal by 15-35ms. Modulates delay time with LFO. Creates pitch variations. Blends with dry signal. Multiple delay lines possible. Phase differences create width.
Musical Applications
Clean guitar thickening. 80s pop and rock textures. Jazz and fusion smoothness. Country guitar sparkle. Ambient and atmospheric sounds. Bass guitar enhancement.
Types of Chorus Effects
Analog Chorus
Uses bucket brigade delay (BBD) chips to create warm, musical modulation. Known for their organic sound and subtle imperfections.
Digital Chorus
Provides clean, pristine modulation with precise control. Often includes multiple chorus types and extensive parameter control.
Stereo Chorus
Outputs to two amps or channels, creating wide, spacious soundscapes. Essential for achieving classic 80s guitar tones.
Multi-Voice Chorus
Uses multiple delay lines and LFOs to create ensemble effects, simulating large groups of instruments.
