Noise Gate Guitar Pedal: A Complete Buyer's Guide

A noise gate guitar pedal reduces unwanted noise and hum from your signal chain. If you're considering buying one, understanding what a noise gate actually does and which models suit your needs will help you make a smart choice. This guide covers the specs that matter, common noise gate types, price tiers, and the pitfalls to avoid when buying.

What a Noise Gate Pedal Actually Does

A noise gate is a tool that mutes your signal when it falls below a certain volume threshold. When you're not playing or when your signal is just background hum or noise, the gate mutes the output. When you play loud enough to cross the threshold, the signal passes through cleanly.

This sounds simple but it's genuinely useful. If your signal chain is noisy (common with distortion, gain-heavy amp setups, or cheap cables), a noise gate removes the noise between notes, leaving only your playing.

Here's the key: a noise gate doesn't affect your tone when you're playing—it only affects the silence. It's purely a utility tool.

Who Actually Needs a Noise Gate Pedal?

Not every guitarist needs a noise gate. They're most useful for:

High-gain players. Distortion and high-gain effects amplify noise along with your signal. A noise gate cleans this up. If you play metal, prog rock, or heavy styles, a gate is genuinely helpful.

Gigging musicians. On stage, background noise and hum become more obvious. A gate ensures your between-note silence is clean and professional.

Studio recording. In the studio, noise is immediately audible and ruins takes. A gate cleans up the signal for cleaner recordings.

Long signal chains. The more pedals and cables in your chain, the more noise accumulates. A gate at the end of your chain cleans this up.

If you play at home with moderate gain and don't have a particularly noisy signal chain, a noise gate isn't urgent. It's a nice-to-have tool that becomes essential once you gig or use high-gain setups.

Understanding Noise Gate Specs

Threshold

Threshold is the volume level at which the gate opens. Below threshold, signal is muted; above it, signal passes through. This is the most important parameter.

A good noise gate lets you adjust threshold smoothly so you can find the sweet spot where background noise is muted but your playing still comes through clearly. You should be able to set it fine so quiet passages still come through while dead silence stays silent.

Look for a gate with smooth threshold adjustment and ideally visual feedback (a light or display) showing whether the gate is open or closed.

Attack and Release

Attack time is how quickly the gate opens when you cross the threshold. Too fast (instantaneous) and you might lose the natural note attack. Too slow and quiet notes get cut off. Ideal attack time is usually 0.5–2 milliseconds for guitars.

Release time is how quickly the gate closes after your signal drops below threshold. Too fast and you get chopping/cutting of notes. Too slow and background noise persists. Typical release is 50–200 milliseconds depending on your style.

A good noise gate lets you adjust both attack and release. This flexibility lets you dial in a gate that sits perfectly behind your tone without affecting it.

Range or Reduction

Some gates have an adjustable reduction level (how much the signal is cut when closed—full mute or partial reduction). Most guitar gates just fully mute, which is fine. If the gate offers partial reduction, you probably don't need it—full mute is simpler and more common.

Noise Gate Types

Standalone Pedals

Single-function pedals that do only noise gate. They're focused, often have excellent controls, and cost £50–£150. Boss NS-1 and NS-2 are standards.

Pros: Dedicated controls, high quality, professional-grade.

Cons: Take up pedalboard space, less versatile.

Multi-Effects with Noise Gate

Larger pedalboards and multi-effect units (Boss ME-80, Line 6 Helix) include noise gate functionality. If you already have a multi-effect unit, you might not need a separate gate.

Pros: Space-efficient, integrated into your system.

Cons: Controls might be less intuitive than a dedicated gate. Gate parameters might be less adjustable.

Amp-Built-In Noise Gate

Some amplifiers include a noise gate built into the effects loop. If your amp has this, you might not need a pedal—just engage it and adjust parameters on the amp.

Pros: No extra pedal needed.

Cons: Limited control compared to a dedicated pedal. Works only with that amp.

Price Tiers and What You Get

Most players get excellent value in the £80–£150 range. Below that, controls are too limited to dial in a perfect gate. Above that, you're paying for pro touring durability and features you might not use.

Common Buying Mistakes

Thinking all noise gates are the same. Attack and release time matter hugely. A gate with poor attack/release settings will chop your tone no matter the threshold. Test the gate's responsiveness before buying.

Buying the cheapest gate without testing. Budget gates with fixed attack/release often chop quiet notes or cut off sustain. Test before buying. A slightly more expensive gate with adjustable controls is worth it.

Installing the gate in the wrong place in your chain. Generally, place a gate at the beginning of your chain (right after your guitar) or at the end (after all effects). Placing it mid-chain can cause unexpected problems. Check the gate's documentation for recommended placement.

Setting the threshold too high. If you set threshold so high that quiet passages get cut off, the gate defeats its purpose. Dial it carefully so background noise is eliminated but your playing comes through completely.

Ignoring attack/release time. A gate with wrong attack time will make your notes feel unresponsive or chop them. If the gate sounds bad, it's usually an attack/release problem, not the gate itself. Test these settings before concluding a gate doesn't work.

Assuming you need a gate immediately. If your signal isn't particularly noisy, a gate isn't urgent. As your gain and cable count increase, or when you start gigging, a gate becomes valuable. Buy it when you actually need it.

Testing a Noise Gate Pedal Before Buying

If possible, test the gate with your actual signal chain. Here's what to check:

1. Set threshold carefully. With your guitar playing quietly, adjust threshold so background noise stops but your playing comes through. Does this adjustment feel intuitive?
2. Play hard and play soft. Loud notes should come through cleanly. Quiet notes should also come through—the gate shouldn't chop them.
3. Check attack and release. Play a note and let it sustain. Does the note come in naturally, or does it feel sluggish? Does sustain get cut off abruptly at the end?
4. Play fast passages. Rapid note sequences reveal whether the gate keeps up. Does each note come through cleanly, or do some get muted?
5. Engage and disengage.** Play through the gate, then bypass it. The difference should be obvious—the gate should only eliminate noise, not affect tone.
