The Silencer – Electro-Harmonix Professional Noise Gate

Advanced Noise Gate pedal for guitar and effects loops

The Electro-Harmonix The Silencer pedal is a sophisticated noise gate designed to effectively eliminate unwanted noise from a guitar, amplifier, or an entire effects loop.

Thanks to its precise settings and flexible operation, it allows you to control background noise while preserving the dynamics and character of your signal.

Ideal for guitarists, bassists, and stage or studio musicians, this pedal integrates perfectly into a pedalboard or a complex effects chain.

Precise noise control for your audio signal

The Silencer offers three essential controls for fine-tuning:

Threshold

Determines the level required to open the noise gate and let the signal pass.
Allows you to adapt the pedal to your instrument and playing style.

Reduction

Controls the level of signal reduction when the gate is active.
Adjustment range: -70 dB to +4 dB.

Release

Defines how long the gate remains open after the signal drops below the threshold.
Adjustable time between 8 ms and 4 seconds for ultra-precise control.

Flexible use – Inline or in an effects loop

The pedal can be used:

✔ As an inline noise gate directly on your instrument
✔ In a full effects loop to clean up your entire sound chain

Connections include:

• 1/4" Input

• 1/4" Output

• Send

• Return

The buffered bypass keeps the effects loop in the signal path even when the pedal is disengaged, ensuring transparent sonic integration.

• Operates on a 9V battery (included)

• Compatible with EHX 9.6 VDC – 200 mA power supply (optional)
