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 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. 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.

Does exactly what it’s supposed to do
Takes any worry out of playing on a small stage and you’re close to your amp No loss of tone Another great pedal from lone wolf blues co
I haven’t tried it on stage yet, but it works great in the basement. I have a 59 Princeton with a ton of crunch. The harp shield allows me to get a lot more volume out of it, and therefore providing even more crutch and compression. So far I’m very happy with it. I’ll find out this week how it works at a live venue. I live in Canada and will be visiting New Orleans in April for the French Quarter Festival. Hoping to make it up your way. Would love to try out a few more petals. By the way, delivery was quick and effortless for me. Thank you.
Able to Crank it Up!
Very cool being able to drive the amp up and get the crunch without the scream…
So far good. Seems to cut feedback well
Three words. It does NOT work! Yes you can stick your mike right into the back of the amp, wow no feedback. Take it on stage .......it is about as much use as a rubber hammer.
