The Fundamental Chorus is a digital emulation of a classic analog chorus, recreating bucket brigade modulation. With 3 types of chorus algorithms to select from, you can get sounds ranging from gentle modulation to 80's tri-chorus.

- Rate: Control the rate of the modulated LFO.
- Depth: Control the depth of the modulated LFO.
- Mix: Control the mix of the effect and the original clean signal. All the way to the left is fully clean, and all the way to the right is fully Reverb.
- Slide Switch – The slide switch allows you to change between 3 different flavors of the pedal.
- Light – Emulates a traditional analog chorus.
- Medium – Adds multiple taps to further modulate a classic chorus.
- Heavy – Emulates a classic Eighties effect, the LCR tri-chorus.

- Bypass Switch – Turns the effect on and off. Hold down to engage tap mode. Hold down again to disengage tap mode.
