TC Electronic Sentry Noise Gate, Pre-Owned in great condition! Original Box included. Sentry Noise Gate is your gateway to a noise-free and fully dynamic performance. Its cutting-edge multiband technology is set to cater to all of your hum and buzz-killing needs and with its highly intuitive design, you'll be dialing out that unwanted noise faster than an Yngwie Malmsteen arpeggio lick. Although extremely simple to use, Sentry Noise Gate's technology is based on the same algorithms as featured in System 6000; TC’s definitive studio processing powerhouse. The pedal also features a classic hard-gate mode along with a loop Send/Return for silencing noisy pedals/amps all without cutting out dynamics or feel. This can even be used for creative sidechaining, so the gate can be in precise sync with other signals. Take control and enjoy the silence!
