Fundamental Ambient is a compact, spacious, and soft ambient reverb with three reverb modes. It offers professional-level tone yet simple controls that are easy to use for a wide range of users, making it the perfect starting point for exploring ambient reverb. With three reverb algorithms, you can go from deep, dark pad-like sounds to lo-fi AM radio sounds at the flip of a switch. Slider Controls ● DECAY - Controls the amount of decay time of the reverb. TONE – Adjusts the tone of the reverb. In Deep and Lush modes it acts as a synth-style low-pass filter cutoff. In Haze mode it acts as a band-pass filter, cutting highs and lows when slid to the right, and preserving highs and lows when slid to the left. ●MIX - Control the mix of original sound and effect sound. 3-way switch Three reverb algorithms ●DEEPDEEP: A dark reverb sound with added low octaves, perfect for creating a murky cave-like sustain or as a hidden reverb. LUSHLUSH: A breathtaking, expansive reverb sound with ultra-long sustain, perfect for creating soft pads and layered single-note soundscapes. HAZE: A lo-fi reverb sound using distortion, sample rate reduction, and bandpass filtering. Ideal for creating vintage or experimental sounds. Trail Mode The Fundamental Reverb is equipped with a Trail Mode. When Trail Mode is enabled, the reverb decays naturally when the unit is turned off. When Trail Mode is disabled, the reverb disappears immediately when the unit is turned off. This can be changed by pressing and holding the switch while powering on.
