Pigtronix Gatekeeper Mini

The Pigtronix Gatekeeper Mini is a compact noise gate pedal from Pigtronix, designed for high-gain rigs where hum, hiss and buzz creep in whenever you stop playing. Delicious Audio described it as "a lightning fast, studio-quality noise gate that locks out unwanted noise from any rig," mercilessly cutting unwanted sounds "at the very instant you stop playing"¹.

It works like any other noise gate: you set a Threshold level, and any signal below it is silenced. Pigtronix built it on ultra high-speed J-FET circuitry to eliminate hum, hiss, buzz and other intrusive non-musical sounds, and the pedal provides 100% attenuation with what the maker calls unprecedented response time¹. It is a mini pedal, sized for tight pedalboards, and it arrived in 2021 as one of four mini-pedals Pigtronix released that year, three of them unveiled during the virtual NAMM show¹.

Where the Gatekeeper Mini comes from

The Gatekeeper Mini is a shrunken version of the full-size Pigtronix Gatekeeper, which Pigtronix unveiled in July 2013. The original was announced as a studio-quality noise gate with threshold and release time knobs, J-FET circuitry, true bypass switching, an army green color scheme and a MAP price of $149². Premier Guitar's launch coverage called it "another piece of word-class analog engineering from Pigtronix"², and Delicious Audio noted its above-average headroom and wide-range threshold control³.

Pigtronix then shrank the design in stages. In 2017 the company released micro editions of several effects, including a small version of the big Gatekeeper with its J-FET circuit⁴. In February 2020, MusicRadar reported Pigtronix announcing three new mini pedals, among them the Gatekeeper Micro, promising a "lightning-fast, studio-quality" noise gate with threshold and release time knobs⁵. The Gatekeeper Mini followed in 2021¹.

The Threshold and Release controls

The Gatekeeper Mini has two knobs, and they divide the work the way most two-knob gates do¹:

Guitar World's noise gate buying guide explains the same arrangement on the Gatekeeper Micro: the threshold knob determines how much signal is needed for the gate to open, while the release knob controls how quickly it closes⁶. GuitarPlayer's guide describes the same split on the Pigtronix Gatekeeper 2, with Threshold determining how much signal opens the gate and the release knob determining how long before it closes⁷.

In practice, a low Threshold setting lets quiet playing through while still muting rig noise; a higher setting clamps down harder, which suits heavily overdriven or distorted signals that sit well above the noise floor. The Release control keeps sustained notes from being chopped off abruptly, since a fast close suits staccato playing and a slower one lets chords ring out before the gate shuts¹.

How it sounds in a high-gain rig

Guitar World's 2026 buyer's guide, which named the Gatekeeper Micro its best compact noise gate, found it "great for keeping things tight and controlled, less so for just general hum reduction, which makes it well-suited" to players who use more gain, while noting it takes time to dial in⁶. That matches the Mini's own positioning: it is built for high-gain rigs, cutting hum and white noise the instant you stop playing¹.
