Equipped with two independent phasers named [ANTE] and [POST]! Although it is simply called a phaser, it is an effect that produces a variety of effects. Swell of Silence!? is a four-stage phaser with a fully analog circuit that can produce sounds ranging from deep, undulating to shallow, detailed sounds. When used in combination with distortion, it produces a swirling sound with low noise, and even when cut with a clean sound, it never loses the pitch or musical tone of the chord work. Swell of Silence!? is suitable for a variety of playing styles and is sure to become a new modulation pedal. One of its distinctive features is the non-oscillating phaser. By controlling "Depth" and "Bias", you can achieve a unique filter effect similar to a half-stop wah.
