An excellent noise gate that is a sleeper due to its woefully unintuitive I/O labeling. I've included a photo of my DIY labels before I removed them for this listing. Use this as a cheat sheet when running it both in front and in the loop for quick and responsive gating.

The TC Electronic Sentry Noise Gate is an advanced, studio-quality noise reduction pedal for guitar and bass. It eliminates hum and buzz using state-of-the-art multiband technology, preserving your instrument's core tone and dynamics while keeping your signal pristine.

Multiband Gating: Utilizes algorithms derived from TC Electronic's acclaimed System 6000 studio processors. It targets specific frequency bands rather than clamping down on the entire signal, resulting in highly transparent and organic noise reduction.

Hard-Gate Mode: Offers a classic, instant-clamp gate for choppy, aggressive metal riffs and abrupt silences.Send/Return Loop: Features an integrated send/return loop, allowing you to create a sidechain or place your dirtiest pedals in the gate's detection loop for maximum precision.

TonePrint Enabled: Allows you to beam custom signature presets straight from your smartphone using the free TonePrint app, or deep-edit gate parameters via the TonePrint Editor on PC, Mac, and iPad.

Onboard Controls: Dedicated knobs for Threshold (when the gate kicks in), Damp (how much the signal is attenuated), and Decay (how long the gate stays open).
