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.

This pedal brings expansive pillowy reverb to the Fundamental Series with three atmospheric modes in a compact size.

Key Features

  • Slide Switch – The slide switch allows you to change between three Reverb algorithms.
  • Trails Mode – The optional Trails mode allows the reverb to continue trailing off after the pedal is disengaged. The Fundamental Ambient Reverb comes with trails mode active by default that can be turned off.

With Ambient’s three reverb algorithms, you can experiment with deep, dark pad-like sounds to AM Radio-like lo-fi sounds with the flip of a switch.

Each Fundamental pedal has three faders for tweaking the sound and a three-way switch for changing the pedal modes.

3-Way Switch

  • 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.

Controls

  • Decay – Control the amount of reverb decay time. Left is the minimum and right is the maximum amount of time.
  • Tone – Shapes the overall tonality of the reverb. On Deep and Lush this controls the cutoff of a synth-style lowpass filter. On Haze this controls the width of a resonant bandpass filter, filtering both high and low end at the right, and allowing more high and low to pass through at the left.
  • Mix – Control the mix of the effect and the original clean signal. The left outputs only the fully clean signal, and the right outputs only the affected Reverb signal.

Distortion

Distortion pedals take your clean guitar signal and transform it into something bigger, bolder, and full of attitude. By clipping the waveform, they add sustain, bite, and aggression, creating that thick, compressed tone that’s powered rock music for decades. From the growling crunch of classic hard rock to the tight, saturated roar of modern metal, distortion is all about energy and presence. It gives every note weight and authority, pushing your amp to its limits and beyond.

There are countless flavours of distortion, each with its own texture and edge. Some sound smooth and creamy, others raw and gnarly like tearing fabric. It’s the sonic equivalent of turning up the heat until the sound cooks — rich, sizzling, and perfectly seasoned to taste. Whether used for rhythm muscle or soaring leads, a good distortion pedal doesn’t just add volume; it adds personality, grit, and that unmistakable sense of power under your fingers.

Octave

An octave pedal shifts your guitar signal up or down by one or more octaves, blending the altered pitch with your original sound to create a fuller, more complex tone. It can add a deep, bass-like layer underneath your playing or a shimmering high octave on top for lead lines and solos. Classic analogue octave pedals often produce slightly gritty, organic sounds, while modern digital versions track more precisely and can offer multiple octave ranges.

Octave pedals are great for thickening single-note riffs, creating synth-style textures, or even mimicking bass parts when playing alone. They pair well with fuzz or overdrive pedals for massive, harmonically rich tones. Whether you’re after vintage Hendrix-style octave fuzz or a modern polyphonic sound that tracks chords cleanly, an octave pedal opens up a world of creative possibilities and adds real weight and character to your tone.

Reverb

A reverb pedal is like the rich sauce that ties every flavour on the plate into one smooth experience. It adds depth, warmth, and atmosphere — the sonic equivalent of a perfectly reduced glaze that lingers on the tongue. Whether you’re after the subtle ambience of a cosy café (spring or plate reverb) or the grand echoes of a cathedral (hall or shimmer reverb), this is where your tone breathes and expands. A touch of reverb can turn a dry sound into something lush and inviting — but pour on too much, and it’s all you can taste. Used with finesse, it’s the finishing touch that transforms your tone from plain to unforgettable.

Synth

A synth pedal transforms your guitar signal into rich, layered tones that mimic the sounds of a synthesiser. Using pitch tracking and waveform generation, it can produce everything from deep bass lines to shimmering pads and futuristic leads. Synth pedals open up a wide creative range, blending the expressiveness of guitar playing with electronic textures, making them ideal for experimental sounds, ambient music, or adding a modern edge to classic riffs.
