The Gatekeeper Micro utilizes ultra-high speed J-FET circuitry to completely eliminate hum, hiss, buzz and any other non-musical sounds from your signal path. The wide range threshold control combines with superior headroom to deliver smooth transient response and warp speed time constants previously available only in rackmount, studio oriented noise gate processors. These extreme performance characteristics allow for musical gating even under the most punishing demands of high-speed metal. The addition of the release time knob allows the user to control how long it takes gate to slam closed. Mercilessly cutting out any and all sounds you don’t want to hear at the very instant you stop playing, the Gatekeeper Micro will allow players to crank up the volume without fear of hearing the annoying 60-cycle hum or white noise that plagues most high gain rigs.
