If you’re a guitar player, you probably understand the frustration of dealing with unwanted noise and hiss in your signal. Whether you’re playing live or in the studio, these extraneous noises can be incredibly distracting and can impact the overall quality of your sound. One of the most effective tools for combating this issue is a noise gate. And one of the most popular options on the market is the MXR Noise Gate.
But have you ever wondered what’s actually going on inside the MXR Noise Gate? How does it work to eliminate unwanted noise while still preserving your guitar’s tone? In this article, we’ll take a deep dive into the MXR noise gate schematic, exploring the different components and their functions. We’ll also discuss how you can build your own noise gate using this schematic, giving you complete control over your signal.
The MXR Noise Gate schematic consists of several key components working together to achieve its noise-reducing magic. At its core, the MXR Noise Gate utilizes a voltage controlled amplifier (VCA) to control the amplitude of your guitar signal. This means that when you’re playing, the VCA allows the signal to pass through unaffected. However, when you stop playing and the signal falls below a certain threshold level, the VCA quickly reduces the signal level, effectively gating out any unwanted noise.
In addition to the VCA, the MXR Noise Gate schematic also includes a trigger circuit and an attack/release circuit. The trigger circuit is responsible for detecting when the signal falls below the threshold level and sending a control signal to the VCA. The attack/release circuit determines how quickly the VCA activates and deactivates, allowing for precise control over the gating effect.
Building your own MXR Noise Gate based on this schematic can be a rewarding and educational experience. Not only will you gain a deeper understanding of how noise gates work, but you’ll also have the satisfaction of knowing that you’ve created a custom tool for your guitar rig. Plus, building your own noise gate allows you to tailor the circuit to your specific needs and preferences, giving you even greater control over your sound.

Pay close attention to the orientation of the components, as improper placement can affect the circuit’s performance. Once the components are securely soldered, proceed to solder the transistors and other semiconductor components.
After soldering all the components, double-check for any cold solder joints or short circuits. This step is crucial to ensure the circuit functions correctly. Once you’ve verified the connections, it’s time to connect the power supply and test the circuit. Use a multimeter to measure the voltages at various points in the circuit and compare them to the values indicated in the schematic. If everything checks out, you’re ready to enclose the circuit in a suitable housing and connect it to your guitar.
Building your own MXR Noise Gate can be a fulfilling and educational experience. It allows you to customize the circuit to your preferences and save money compared to purchasing a pre-built pedal. By following the MXR Noise Gate schematic and carefully soldering the components, you’ll have a reliable noise gate that enhances your guitar playing and takes your tone to the next level.
What is a Noise Gate?
A noise gate is an audio device or software plugin that is used to control unwanted noise in audio signals. It is commonly used in recording studios, live performances, and audio production to reduce background noise and improve the overall sound quality.
A noise gate works by setting a specific threshold level, below which any audio signals will be suppressed or completely muted. When the incoming audio signal falls below the threshold, the noise gate closes and blocks the sound from passing through. This helps to eliminate background noise, such as hiss, hum, or ambient room noise, that may be present in the audio signal.
The effectiveness of a noise gate relies on properly setting the threshold level to match the desired sensitivity. If the threshold is set too low, it may cut off desired audio signals, resulting in an unnatural sound. On the other hand, if the threshold is set too high, it may not effectively suppress the background noise.
Modern noise gates often come with additional features, such as attack and release controls, which allow for more precise control over the gating effect. The attack control determines how quickly the noise gate will react once the threshold is crossed, while the release control determines how long the gate remains closed after the audio signal falls below the threshold.
In conclusion, a noise gate is a valuable tool for audio professionals and musicians who want to improve the quality of their recordings or live performances by reducing unwanted background noise. It helps to create a cleaner and more focused sound, allowing the desired audio signals to shine through without interference from noise.
Key Components of the MXR Noise Gate
The MXR Noise Gate is a popular guitar effects pedal that helps to eliminate unwanted noise and hum from a guitar signal. It achieves this by effectively cutting off the signal when it falls below a certain threshold. To understand how the MXR Noise Gate works, it is important to familiarize yourself with its key components.
Threshold control: The threshold control on the MXR Noise Gate determines the level at which the gate will open and allow the signal to pass through. By adjusting this control, you can set the sensitivity of the gate to best suit your needs. Higher settings will result in a more pronounced gate effect, while lower settings will allow for a more subtle noise reduction.
Decay control: The decay control determines how quickly the gate closes after the signal falls below the threshold. This control allows you to shape the release of the gate, controlling how long it takes for the signal to fade out after it has been silenced. Turning the decay control clockwise will result in a longer decay time, while turning it counterclockwise will result in a shorter decay time.
Indicator LED: The MXR Noise Gate features an indicator LED that provides visual feedback on the status of the gate. When the LED is illuminated, it means that the gate is open and the signal is passing through. When the LED is off, it means that the gate is closed and the signal is being suppressed.
Input and output jacks: The MXR Noise Gate is equipped with standard 1/4″ input and output jacks, allowing you to easily connect it to your guitar and amplifier. The input jack accepts the guitar signal, while the output jack sends the processed signal to the amplifier. These jacks are essential for integrating the noise gate into your guitar rig.
Power supply: The MXR Noise Gate can be powered by an AC adapter or a 9-volt battery. It is important to ensure that the noise gate is properly powered in order to function correctly. The power supply options make it convenient for use both in the studio and on stage.
All of these key components work together to make the MXR Noise Gate an effective tool for managing noise in a guitar signal. Whether you are playing live or recording in the studio, the MXR Noise Gate can help you achieve a cleaner and more professional sound.
