The AUTO REVERB offers you three expansive and precise reproductions of the most frequently used types of reverberation. PLATE algorithm is characterized by slightly metallic and bright overtones typical of studio plate reverbs. The bright overtones can, of course, be tamed or exaggerated with the TONE and FILTER knobs. SPRING algorithm precisely mimics the drippy response of guitar amplifier spring tanks. The tonal response is even more metallic than the PLATE reverb. HALL algorithm can place your input signal in a physical space—from small reverb chambers to infinitely huge halls. The smooth diffusion can achieve synthesizer pad-type sounds on high DECAY settings.
