A good noise gate should be there to silence away the hum, hiss, and background noise that an effect chain inevitably brings. It should turn on at a certain sensitivity threshold keeping things quiet. Otherwise it should remain signal transparent allowing all your playing to go through. The Joyo Noise Gate JF-31 pedal does just that. Above the threshold level, the noise gate kicks in and silences your entire signal. Useful for when you've stopped playing and don't want to hear that 60 cycle buzz especially with overdrive or distortion in your chain. No need to spend a lot of money for such a simple function. Joyo Noise Gate keeps things quiet for a very low price. Features: Threshold Control True Bypass Solid Aluminum Alloy Case Uses 9V Battery or Adapter(nerther included)Note: Power supply not included.
