The Fortin Amplification Mini Zuul is a practical Noise Gate effects pedal for Electric Guitar and Bass, which not only provides a pleasant silence during breaks, but also supports the playing of accentuated staccato riffs. In addition to the threshold of the gate circuit, the threshold control also determines its dynamics, so that the Noise Gate closes and opens faster at higher settings. Another special feature of the Fortin Amplification Zuul is the side-mounted "key" input, which can be used to control the Noise Gate using an external signal.
