Shut the gate on feedback with the Harp Shield. The Harp Shield works by using noise gate technology to disconnect the mic when you are not playing, suppressing feedback.

Now with improved silent gating

Feedback occurs when audio signals from the amplifier's speaker are picked up by the microphone and fed back into the amplifier where it is amplified again causing a vicious cycle. The Harp Shield will prevent this process from ever starting by using noise gate technology. The Harp Shield is designed to mute the microphone when you are not playing by decoupling the microphone from the amplifier, thus preventing feedback. With the Harp Shield, your microphone is muted when not playing. As you begin to play, the Harp Shield will un-mute and allow your signal to pass through to the amp; when you stop playing, the pedal automatically mutes the microphone to prevent feedback. The pedal has a SENSITIVITY control to prevent background noises from opening the audio path and inducing feedback. When using this pedal, it is still necessary to use proper microphone handling techniques to help prevent feedback while playing. The Harp Shield differs from guitar noise gates in that the gate range is set for microphone levels and the fact that you will not lose any tone.

The pedal requires a 9v battery or a 9vdc power adapter. The AC adapter requirements are 9vdc with a minimum 100mA output and a 2.1mm x 5.5mm connector with a negative center and positive outside. Current draw is 9.2ma. The battery is switched OFF when an external power supply is used, and the IN jack acts as the ON/OFF switch and the pedal is ON as long as there is a cable plugged into the IN jack. Power adapter is not included.

Harp shield

Truly a trustworthy company with great products! I wasn’t sure about this product at first until I got it into the garage with three guitars and a base with lots of vocals. So much noise in a small space but I had no issues with feedback.

Harp Shield works but……

I really like the way the Harp Shield prevents feedback, but I don’t like the clicking sound in the amp when I blow the Harp.
