ABOUT
Audio signals from the amplifier’s speaker are picked up by the microphone and fed back into the amplifier where it is amplified again resulting in what we know as feedback; 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 unmute 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. In the event that feedback does occur, just press the footswitch (a momentary switch) to reset the pedal and stop the 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.

UPDATE 10/21/12 - In response to some questions that I have received, I am adding the following information. The pedal requires a minimum level of signal from the mic to open the gate and when the signal drops back down to the same minimum level the gate will close. This function is not noticeable with the sensitivity set low (CCW) but is noticeable with the sensitivity set high (CW); but this is only a factor when playing softly. The pedal is not a silver bullet; it has its limitations. One is when the room acoustics are horrible for feedback, small and hard-walled (like a spare bedroom); it does not help at all. The second is a tight band setting that is very loud (all too common); this is due to the fact that when the sound levels hitting the microphone are too high, it can keep the gate open. In the last instance, one must also roll off the volume on the microphone when not playing.

SETTINGS
The only control is the SENSITIVITY control. With the control all the way CCW, the pedal is most sensitive and will allow virtually any signal to pass through the microphone. But the mic will be more susceptible to low-volume noises opening the pedal and inducing feedback. Turning the control CW, increases protection from feedback by requiring a higher level of audio to unmute the microphone and pass the audio. With the control turned too far CW, you may not be able to pass audio while playing softly. The footswitch is not a bypass switch; the foot switch is a momentary, non-latching switch, pressing the switch mutes the microphone (kills the audio) and resets the gate, stopping feedback. The Harp Shield should go first in your pedal train.

POWER
The Harp Shield operates off of a 9V battery or a 9V DC power adapter. To make it all just a little easier Lone Wolf is offering a power supply for US and EURO customers to power your pedal. 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.

FEATURES
  1. SENSITIVITY control
  2. Feedback-killing footswitch
  3. 9V DC input (barrel with a negative center)
  4. High impedance buffered input
  5. Pedal ON/OFF LED
  6. Reverse voltage polarity protection
  7. 9V battery operation
  8. 5-year warranty on parts and labor
  9. If not satisfied, return within 60 days for a refund of the purchase price minus shipping and 4% credit card transaction fee

REVIEWS


Jason Ricci:
"Randy from The Lone Wolf Blues Company has made a new Anti Feed Back pedal. The Pedal is simple in design with one knob and extremely effective at fighting feed back. I would go as far to say that it eliminates feedback better than any existing devices I have tried whether they were aimed at amplified harmonica playing or other wise. The Pedal is small and a nice gold color, it's cheap too, hundreds cheaper than comparable boxes. Randy is a great dude, has a fantastic return policy and sincerely and truly cares what we all think of his stuff. The Harp Sheild is True Bypass (No signal loss) and the same size as the other LWBC pedals (Except the Harp Attack). It can also be powered with a 9v converter or a battery! A few have been made (mine) and some sold instantly at SPAH but they're here. For those of you who enjoyed the extra distortion/compression that came with the other blue AFB made, the 'Harp Shield' coupled/ in conjunction with the 'Harp Break' or 'Harp Attack' by LWBC will produce the same results with more user managability and control. For those who disliked the old AFB designs and its tone changing properties the 'Harp Shield' DOES NOT CHANGE TONE!”

Johnny Sansone:
"Randy at Lone Wolf Blues Co has done it again! Dialing up your killer harp tone on any size amp just got a whole lot easier with the new Harp Shield pedal, keep the tone, kill the feedback and keep up with your guitar players volume, you are going to love this pedal as much as I do. Thanks again Randy!"

French rock harmonica sensation Marko Balland:
"The Harp Shield is a real good anti-feedback pedal, when compared to the other pedals on the market 'Kinder or FBX Sabine'. The Harp Shield does not compress the sound. It absorbs the frequency with the only one potard (button). The Harp Octave is a distortion with a harmonics, a little bit like a fuzz pedal, it's the best pedal for the rythmics, it's my favorite! The Harp Break is a good pedal for distortion, with a great sound real effective for bass, it is very good for the Blues or Rock."   Visit Marko's site

From a customer in Sweden:
"Have run the first test of harp shield ... Göta Petter.
Just what I needed, can squeeze in a lot more, I've split the output at the end of the pedalboard, so half goes to my amplifier and half via my harp attack right into the PA... no problems whatsoever."


From Jake Friel:
"I would like to thank you for letting me be one of the first to purchase the "Harp Shield"at this past Spah. I ABSOLUTELY LOVE IT! Its amazing, it really is the perfect feedback box, I personally think it is the best feedback controller I have ever used. Now the reason I have not posted the promo video, is that I wanted to gig with it to see how it held up against my (loud) band haha... and believe me it did!! for the last few weeks I have also been using the Harp Break..and I love that one too!! in the attached video I demonstrate how both of them sound and I'd love for you guys to post it on the website!! Cheers from Ohio, Jake Friel"

From Robert Weir:
"Just like to thank you for the Harp Shield pedal. I found your description of it's performance to be accurate. I've used it at band practise at an old timber country hall and have found it very effective. When the band played loud I was clearly the loudest instrument with absolutely no feedback. The added bonus was hearing my amp at a level never previously heard before, where it broke up like a small wattage amp. It sounded great. A 2 by 6V6 20watt amp breaking up like a fender champ. Amazing sound. It has taken me a couple of weeks to get a handle on it at the local jam night. At the start of the night there is no need for it, but as the night wears on and it gets progressively louder, I plug it in front of the your Harp Delay pedal that I always use. Last night on the last play it was ear piercingly loud with three electric guitars and a drum kit on a small stage. Through playing technique, moving away from my amp a little and not standing in front of it, and rolling off the inline volume control on my shure CR mic when not playing, I was able to keep up with the loud guitars. Something I have never been able to do. And not blowing my lungs out. Plus the amp was breaking up really well and sounding better than it ever did, with great tone. Thanks again Randy for the Harp Shield. Always a pleasure dealing with you."

From Daddy Rich in Clarksdale, MS:
"Howdy Race Fans, after playing harp for 5 long years now, (it's hours not days right?) I quickly realized that after learning how to properly set up my reeds and learning to play all of the bends that FEEDBACK would become my GREATEST ENEMY! I've been playing guitar for about 23 years and teaching at the Delta Blues Museum in Clarksdale, MS for close to a decade, and even with all my experience, EVIL Mr. FEEDBACK always seemed to be getting the best of me! I tried every rack mount and pedal device for guitar but with minimal success. I even tried the expensive sacred 'BLUE' pedal, but I must agree with Jason that the HARP SHIELD is superior for several reasons:

1. The Cost is 1/3 of the 'blue' pedal and much easier to 'attain' no offense to the gentleman.
2. The Noise Gate circuitry is the BEST I've ever seen bar-none and specifically made for Harp players.
3. Ease of use with just one Sensitivity Knob which works fantastically and the great 'panic button' foot switch is really nice to have just in case but you'll see that you'll rarely need to use it because of the superior gate technology.
4. It's just a GREAT product that does what is says, it's a wonderful design and I think every Harp player should have at LEAST this pedal in their setup. I don't think I'll be able to go back after using the HARP SHIELD. Be forewarned! This pedal is addictive and will inspire you to play wonderful FEEDBACK FREE riffs for hours and hours.
And lastly:
5. Do it for the FANS!!!! They don't want to hear all that squealing and howling from your Harp Amp for goodness sakes!!!! Geeze!!! ;)

Thanks so much Mr. Randy for a wonderful product! I'll be taking this pedal with me to the IBCs in Memphis January 2013 representing the Indianola Blues Society. Don't be surprised if you become overwhelmed with orders around the beginning of February!!!"
-peace, Rich
