There are times when your music calls for single-ended noise reduction…that softer version of noise elimination that allows your sustain to ring out, unaffected, while getting rid of creeping hiss and circuit noise – and that is what Rocktron’s Guitar Silencer does so well. This stomp box provides BOTH of these noise reducing methods in one simple pedal that takes a minimum of space on your pedalboard. Part of the Rocktron Boutique Series of stomp boxes, this pedal design comes in a rugged metal chassis with eye popping retro custom design artwork. This is a TRUE BYPASS pedal: when you turn it off…it is out of your signal path! As an incredible bonus, you can add True Bypass to your favorite distortion pedal when adding the Guitar Silencer to your setup. Controls for the Guitar Silencer include GATE, which is the Threshold at which the noise gate portion of the effect will clamp to silence. The HUSH control determines the Threshold of the noise floor you want the HUSH portion of the effect to reduce. If you own a high gain amplifier this is a must have pedal, it’s a sophisticated noise gate. In excellent condition, home studio use only, and the original box is included. Asking $85. Thank You for looking.
