Caline CP-39 NOISE GATE Guitar Effects Pedal with Caline CP-03 18V 2A Noise Filter Yet another great pedal from Caline! The Noise CP-39 is a noise gate pedal which can help reduce the noise hum and buzz of other pedals (especially high gain distortion) in your pedal chain. There are two main controls. The sensitivity control dictates the level when the noise gate kicks in. At higher settings anything below aggressive strumming will be cut. The two way selector switch controls if the gate kicks in aggressively switch a steep volume cut, or more softly with a gradual cut. Runs off a 9v power supply. Features: -The noise gate pedal is for reducing the noise hum and buzz of other pedals(especially high gain distortion) in your pedal chain. -2 working modes: Hard(reduce high frequency sound) & Soft(reduce low frequency sound), allows you to have more excellent tone. -One control knob for adjusting the volume of the noise reduction. -True bypass, and with LED light for indicating effects or bypass status. -Aluminum alloy shell, durable and sturdy.

Dunlop - M195 Noise Gate Love to crank up those pedals? Love to crank up multiple pedals? Then you know how critical this pedal is in your chain. The MXR Noise Clamp pedal puts the kibosh on hiss and noise from your signal chain. It includes its own effects loop, which effectively lets you kill noise across your entire signal chain. A single Trigger knob lets you set the threshold at which the Noise Clamp activates, and a green LED lets you know when the gate is active. Sounding great is about more than great tone; use the Noise Clamp and keep your rig sounding great between the notes too.

Crank your stomp pedals to the extremes without the fear of any hiss or excess noise with the MXR Noise Clamp. By sensing your guitar's dry signal, The Noise Clamp reduces the noise level within the effect loop, coming down hard on even the noisiest signals. A single Trigger knob allows you to set the volume threshold at which the pedal is active, and a green LED shows whether the gate is on/off. This bad boy is capable of reducing Noise up to 26dB, maintaining riff definition at extreme gain levels.

The NS-2 effectively eliminates noise and hum of the input signal while preserving the original sound's tonality. Noise Suppressor/Noise Gate Guitar Pedal

Estimated delivery time: working days (Imported from the UK) - T&C's Apply Please note that all Christmas gift orders need to be placed before the 14th of November to ensure that they are delivered to you in time. This item includes free delivery within South Africa. The NS-2 can be connected in two different ways. You can connect the NS-2 last in your chain of effects. The output of the previous pedal goes to the NS-2 input jack. Wire the Output jack of the NS-2 to your amp. The NS-2 can also be wired like an effects loop, which allows you to kill your entire signal chain just by stomping on the NS-2. Take the Send output of the NS-2 into your first pedal. Take the output of your last pedal and wire it to the Return jack of the NS-2. The NS-2 uses an intelligent circuit to differentiate between the sound of the guitar and noise. The NF-1 simply cut all sound when it became weaker than a threshold value. The NS-2 attempts to let the sound of the guitar through while re-moving the noise.
