Part of the Oklahioma-based company’s first affordable pedal line, the Walrus Audio Fundamental Chorus is a bread-and-butter digital effect featuring three faders instead of knobs.

The controls are for Rate, Depth, and Mix, while a switch delivers three modes voiced after lush analog units, multiple-tap chorus, and the classic Tri-Chorus from the ’80s.

Walrus Audio Fundamental Chorus, Builder’s Notes

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

Rate: Controls the rate of the modulated LFO. A higher rate will produce a faster and more pronounced pitch modulation, while a lower rate will produce a slower and more subtle effect.

Depth: Controls the depth of the modulated LFO. This affects the amount of pitch modulation applied to the affected signal.

Mix: Controls the mix of the affected signal and the original clean signal. All the way to the left outputs a fully clean signal, and all the way to the right outputs only the modulated signal.

Slide Switch – The slide switch allows you to change between three different flavors of the pedal.

Light – Emulates a traditional analog chorus with warm, lush, and organic tones.
Medium – Adds multiple taps to further modulate a classic chorus.
Heavy – Emulates a classic Eighties effect, the LCR tri-chorus, which is known for its rich and complex modulated sound.
