About This Listing

A sophisticated noise gate that can tame a single pedal or an entire effects loop! The Silencer’s three-control layout provides precise fine-tuning to fit your system, axe and playing style. Threshold adjusts how much level is required to open the noise gate and allow a signal to pass thru. Reduction regulated the degree to which the gated signal is reduced and is variable between -70dB and +4dB. Release controls how long the gate remains open after the signal drops below the Threshold. Release time is variable between 8ms and 4 seconds.

I/O includes ¼ inch Input, Output, Send and Return jacks. The footswitch selects whether The Silencer is engaged or in bypass mode; buffered bypass allows the effects loop to remain in your signal path when the gate is bypassed. A built-in AC jack accepts a standard power supply like the EHX 9.6DC unit (optional) and the pedal comes with a 9V battery.

The Silencer can be used as an inline noise gate or it can gate an entire effects loop. Whether you play with a single distortion pedal, or an entire board of effects, noise can be a problem. With control over threshold, noise reduction and release time, The Silencer can be fine tuned to fit your system, instrument and playing style to remove unwanted noise.


THRESHOLD Knob – Controls how much level is needed to open the noise gate and allow your signal to pass through. At full counter-clockwise the gate remains open and passes all signal through. As you turn THRESHOLD clockwise more level is needed to open the gate.

To tune the THRESHOLD knob, we recommend you start with THRESHOLD set to its minimum position, REDUCTION set to maximum, RELEASE set to minimum, and The Silencer’s LED lit. Turn up the volume knob on your guitar but hold the strings to stop any feedback. You should hear noise coming through your amplifier. Turn up the THRESHOLD knob until the noise disappears, then continue to turn it up just a little more; this setting makes for a good starting point.

REDUCTION Knob – Controls how much the gated signal will be reduced. Reduction is variable between -70dB at full clockwise (for maximum noise reduction) to +4dB at full counter-clockwise (yes you can boost the noise instead of reducing it if you like). You may find setting REDUCTION between 12 o’clock and 3 o’clock produces a more natural gating effect than it does at maximum.

RELEASE Knob – Controls the speed of the envelope signal that closes the gate after the input signal drops below the THRESHOLD setting. RELEASE time varies from a quick 8ms at full counter-clockwise to a slow 4 seconds at full clockwise. Start with a RELEASE setting of 12 o’clock for a natural sounding gate effect.

FOOTSWITCH and LED – The Footswitch selects whether The Silencer is engaged or in buffered bypass mode. When the gate is engaged, the LED is lit. The effects loop remains in your signal path while The Silencer is bypassed.

INPUT Jack – Plug your instrument into this ¼” jack which is the main audio input for The Silencer. The input impedance is 2MOhm.
OUTPUT Jack – The OUTPUT jack is The Silencer’s main audio output. The gated signal exits through the OUTPUT jack. The output impedance is 300Ohm.

SEND Jack – Connect the SEND jack to the beginning of your effects loop. The output impedance is 300Ohm. The SEND jack outputs a buffered version of the signal present at the INPUT jack at all times. If you do not need to use the Silencer’s effects loop, the SEND jack could also be used to split the input signal.

RETURN Jack – Connect the end of your effects loop to the RETURN jack. The signal preset at the RETURN jack is gated by The Silencer. The input impedance is 1MOhm. If you are not using the effects loop and prefer to use The Silencer as an inline gate, do not plug anything into the RETURN jack.

9V Power Jack – Although The Silencer accepts 9V Batteries, it can also be powered from an Electro-Harmonix 9.6DC-200BI power supply. Plug the output of the AC adapter into the 9V power jack located at the top of the Silencer. The Silencer draws 22mA at 9VDC with a center negative plug. The Silencer accepts Boss® and Ibanez® style AC Adapters.

To change your 9-volt battery, you must remove the 4 screws on the bottom of The Silencer. Once the screws are removed, you can take off the bottom plate and change the battery. We recommend 9V alkaline batteries. Please do not touch the circuit board while the bottom plate is off or you risk damaging a component.
