TC Electronic Sentry Noise Gate Guitar Effect

TC Electronic Sentry Noise Gate — Multiband Noise Suppression for Guitar and Bass

The Sentry Noise Gate is a professional-grade multiband noise gate pedal that brings studio-quality noise suppression to the pedalboard. Built around TC's System 6000 algorithms, this pedal eliminates hiss, hum, and unwanted noise floor between notes without chopping off sustain. The Sentry Noise Gate is the right choice for guitarists and bassists running high-gain rigs who need clean silence between phrases.

What sets this model apart from conventional noise gates

What sets this model apart is its three-band architecture, independently gating low, mid, and high frequencies for more natural decay than full-band gates. The mono Send/Return loop routes noisiest pedals through the Sentry, so the gate triggers from the clean direct signal.

Two gating modes plus TonePrint customization

Two gating modes ship onboard alongside TonePrint, giving players a usable setup out of the box and unlimited editor customization.

• Multiband (Hiss) Mode: 3-band frequency gating — targets noise in specific ranges while letting notes ring naturally
• Hard Gate Mode: single-band classic gate — aggressive start/stop cut-offs for modern metal players
• TonePrint Editor for Mac, Windows, and iPad — unlocks deep parameter control and downloadable artist presets

Three-knob top panel for hands-on control

The top panel keeps adjustment simple while offering the flexibility needed for complex rigs.

• Threshold: gate trigger sensitivity — sets the level at which the gate opens to pass your signal
• Damp: attenuation depth — controls how aggressively the gate closes when no signal is detected
• Decay knob — regulates how naturally notes fade after the gate begins closing

Bypass options and pedalboard connectivity

Built-in routing flexibility includes both bypass modes plus a dedicated effects loop for noisy pedals or sidechain use.

• True Bypass: selectable via internal DIP switch — keeps the signal completely untouched when off
• Buffered Bypass: alternative internal switch position — preserves signal integrity across long cable runs and large boards
• Send/Return Loop with mono 6.35 mm jacks — isolates noisy pedals or enables external sidechain triggering
