Walrus Audio adds Fundamental Ambient reverb pedal with sliders and three modes

Walrus Audio announced the Fundamental Ambient on March 19, 2024, adding a reverb pedal to its entry-level Fundamental series¹². It is the ninth pedal in the series and the second reverb in the lineup, following the Fundamental Reverb³⁴.

The pedal has three sliders labeled Decay, Tone and Mix, plus a three-position switch for selecting the Deep, Lush and Haze modes¹⁴. Mix sets the blend between the reverb and the incoming signal, and the pedal can run fully wet¹. Decay sets the size of the reverb and how long it takes to die out¹. Tone works differently by mode: on Deep and Lush it acts as a "synth-style" low-pass filter controlling cutoff frequency, while on Haze it controls the width of a resonant bandpass filter, filtering out more highs and lows as the fader moves right¹.

The modes are described as follows:

The Fundamental Ambient runs in trails mode by default, so the reverb decays naturally when the pedal is disengaged; holding down the footswitch until the LED flashes turns trails on and off¹. Guitar Pedal X reports trails can also be set via a power-up sequence³. The pedal is mono³. It has top-mounted jacks and a side-mounted power input, and the units are designed and made in the USA¹.

The US list price is $129¹². Guitar Pedal X notes that most of the Fundamental series is priced at $129, with only the three gain pedals at $99³. Gearnews lists a GBP 125 / EUR 145 MSRP alongside a $99.00 figure in an affiliate listing⁴.

Walrus framed the pedal's purpose in its own words:

Guitar World noted the $129 price sits below the company's own $219 Slö Multi Texture Reverb². Guitar Pedal X described the Ambient as distinct from the earlier Fundamental Reverb's Hall, Spring and Plate sounds, and said the mono design limits stereo rigs³.
