A lightning fast, studio-quality noise gate that locks out unwanted noise from any rig. Featuring Threshold and Release knobs, Gatekeeper provides 100% attenuation with unprecedented response time and utilizes ultra high-speed J-FET circuitry to completely eliminate hum, hiss, buzz and any other intrusive non-musical sounds from your signal path. Its wide range Threshold control combines with exceptional headroom to deliver smooth transient response previously available only in rackmount, studio-oriented noise gate processors. The addition of the Release knob allows the user to control how long it takes the gate to slam closed.
