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.

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 Harp Shield operates off of a 9V battery or a 9V DC power adapter. The DC adapter requirements are a 9V DC with a minimum 100mA output and a 2.1mm x 5.5mm connector with a negative center surrounded by a positive outside. The battery is switched OFF when an external power supply is used, and the unit is always powered whenever the mic is plugged in. The power adapter is sold separately.

Dial it in.

Great noise gate pedal for that dirty harp tone. I think the type of amp you have plays big role with where the sensitivity dial should be. But I’m really satisfied with it. Worth the purchase for sure!

Helps Stop Feedback

It helps quite a lot but I still have to cut the volume on my Bulletini mic. I am still trying to find the sweet spot with my harp, amp, mic, and pedal combo. The pedal works well with my lower impedance mics but I still have to cut the volume way back on a hot mic. I'm still searching for that perfect tone and I'm sure it will come to me eventually.
