For the Fundamental Series, we challenged ourselves to design a set of pedals with the tonal integrity that’s required to live on a professional’s pedalboard, but with simplified controls friendly enough for even the newest effect pedal users. Each Fundamental pedal has 3 sliders for tweaking the sound and a three-way switch for changing pedal modes. The result is a line of 8 pedals that will keep you covered from your first band practice all the way to a sold-out arena. Designed and assembled at Walrus Audio headquarters in OKC, OK.

Fundamental Chorus

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.

Bypass LED - Illuminated when the effect is engaged, and will blink with tapped tempo when tap mode is engaged.

Trails Modes – Hold down the stomp switch when applying power to the pedal.

Input Jack - 1/4 inch cable from instrument.
