Walrus Audio Fundamental Ambient is a reverb pedal with three huge, atmospheric, ambient reverbs in a compact and easy to use size.
Because vast ambient sounds shouldn’t just be for larger pedals with vast price points, the Fundamental Ambient brings expansive pillowy reverb to the Fundamental Series with three atmospheric modes in a compact size.
It offers a great entry point into ambient exploration with the tonal integrity to live on a professional’s pedalboard but with simplified controls friendly enough for even the newest effect pedal users.
The Fundamental Ambient provides three different atmospheric reverb algorithms to explore beautifully vast and lush soundscapes with plenty of decay time for pillowy soft pad-like decay. Deep – A dark ambient reverb with an added low octave, perfect for creating murky, cavernous sustain or adding a touch of moody atmosphere. Lush – A breathy, expansive reverb featuring ultra-long sustain. Perfect for generating silky pads and immersive soundscapes with every note. Haze – A textured, lo-fi reverb featuring distortion, sample rate reduction, and a resonant bandpass tone control, great for vintage or experimental tones.
The three modes can be controlled and seasoned to taste with the tone, mix and decay knobs. The Ambient Reverb comes with trails mode active by default. With trails mode active, your reverb decay will fade off naturally after turning the pedal off. With trails mode inactive, the decay abruptly cuts off when you turn off the pedal.
Walrus Audio Fundamental series
For the Fundamental Series, Walrus has designed 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 Oklahoma, USA.
Walrus Audio from Oklahoma is the go-to brand for guitarists who want to go beyond the ordinary. Their pedals aren’t just technically impressive—they’re visually stunning too. Whether you’re after ambient reverbs, glitchy delays, or gritty fuzz, Walrus delivers effects packed with personality and ease of use.
Models like the Slö Multi Texture Reverb, ARP-87 Delay, and Julianna Chorus show that Walrus knows how to fuse classic effects with modern features. Think stereo outs, tap tempo, presets, and expression control. But most importantly—they sound amazing.
