Product Information

We appreciate Jason lockwood letting us offer you this great pedal.

In Stock:  Black 9V and Black Hard Wired and Blue 9V and Blue Hard Wired and Red 9V

If we do not have the pedal in stock it will take about a week or so to get them in.

The Squeal Killer has 2 options for power supply: hard wired and 9v.

The Hard Wired option has a power supply that plugs into your wall and can be ordered for any country’s power mains.

The 9v option is the more “typical” guitar effects power supply which is a 9v DC jack on the pedal which requires a Center Negative (typical effects pedal polarity)with  at least 300ma power supply. A good example is the One Spot. Note: the 9v option does NOT run on a battery

Outside the USA buyers. Please make sure to let us no your power needs? Please keep in mind regardless if you order from us or Jason Lockwood, there will be a "build time" Keep in contact with us via email.

The info below is taken from The Squeal Killer site.

Since the beginning of electrified harmonica, there has been an on going battle between tone, stage volume, and feedback.

I cannot count the number of times a harp player has walked off a stage frustrated because they were drowned out by the other instruments. This is particularly common during jams or in clubs where the sound engineer does not provide instrument mics. The fact is, regardless of talent, it is very difficult to play electrified harmonica loud enough to actually feel part of the band or be an actual equal in comparison to other instruments.

In recent years, there have been several boutique amplifier companies that have made amps designed specifically for harmonica players. More often times than not, these are priced way beyond the budget of the average harmonica player. This is not a knock or criticism of those companies. They make very good amps. However, the fact is that with The Squeal Killer in combination with a standard, less expensive tube amp you can achieve the same or, in my opinion, a better and more natural tone for a fourth of the cost.

Now, I would be foolish to try and challenge all of the past and current harp legends and players that can nail that tone with a number of different amps/mics/set ups. But challenging their tone or even your tone is not the intention. Fact is that even the legends have/had an issue with volume when playing live.

SO, SPEAKING OF TECHNIQUE…

The Squeal Killer, and nothing else for that matter, will ever trump technique. I will never state otherwise. But a very close second is the rig you play/learn/practice on. I have yet to meet a harp player that does not begin playing without a very distinct tone in their mind that they want to achieve. Often it is one of the Walters or Clarke or Wells. Point being, in order to want to continue to learn/play, you have to be able to achieve that tone or, in many cases, you become frustrated and quit/put it down.

SO, IS IT THAT GOOD?

The Squeal Killer is almost too good to believe quite frankly and was discovered/patented during a build of a custom amplifier by Stella Vee Amplification for a musician who wanted both a guitar and harmonica amp in one. To date, it is the only tube driven feedback reducer that is designed exclusively for the electrified harmonica. It is very passive – your amp’s tone remains…only louder.

There are no buttons or knobs or levels to change. You simply plug it in and then be amazed how far your volume knob is being turned up.

I have personally tested and heard The Squeal Killer on the following amps and with a Turner or Astatic mic: 1959 Bassman, 1965 Vibrolux Reverb, 1966 Princeton Reverb, ’59 Bassman Reissue, Fender Champ, 1966 Fender Twin Reverb, countless Harmony and National amps. On average, each of the amps went from peaking out at around 3-4 on the Volume knob to around 8-9 or around a 3db increase (33% more perceived volume).

The fact is that it has worked on a very wide range of amps. Does it work on every single amp ever made? Of course not and here is why.

You need “headroom” in an amp’s design to get the full benefit from The Squeal Killer. A 5 watt amp has a very limited range to offer whereas a 59 Bassman has a huge potential of power to tap. Likewise, there are amps that have been made that have a much higher input impedance than say a typical post 57 Fender design. These higher impedances lower headroom and are counter effective to gaining more volume.

Likewise, if you own an amp that is already “modified” for harp or built specific for harp, you may not experience the same results.

I am the inventor of The Squeal Killer and would be happy to discuss its effects with any of you and, more importantly, the expected results on YOUR amp.

Again, if you have any concerns given what you have just read, please ask about what YOU can expect with YOUR amp.

Mostly, I am very excited to offer such a product to the harp player as it has always been my favorite instrument.

If you have any questions at all, please ask before you purchase. I would be happy to speak to you/email you with a very specific answer to any of your questions.

Simply put...you will be able to obtain volume levels that you have never been able to get prior to using this pedal.

 

THE TECH

 

For those that like the technical details…

The Squeal Killer is a patented, tube driven feedback eliminator that operates on a 120v to 6v transformer (included) or a typical 9v (power supply not included). Non US customers that require a different wall voltage can request so in the order. There is no issue accommodating your country’s power mains,

Each order contains the following:

  • Hand wired and assembled in the USA
  • 12at7 (installed)
  • Carbon Comp resistors
  • Sprague capacitors
  • Switchcraft jacks
  • 120vac/6vdc transformer (hard wired) or 9v Jack (power supply not included)
  • Your Color Choice

Given the very low voltage on the tube and if properly cared for, it is likely to last a lifetime.


The Squeal Killer requires a typical “stock” guitar amp gain design in the preamp. In other words, 12ay’s and 12au’s in any preamp location will not work well in most cases.

The Squeal Killer is built by Stella Vee Amplification in Louisville, KY.

Questions and any and all comments are welcome. You can expect as long or short of a conversation depending on your needs as a customer and a very high level or service.

TESTIMONIALS

“Playing harmonica, using amps and mics, feedback has always been an issue. While trying to get good, fat tone with enough volume and no feedback is a challenge on stage. The Squeal Killer has taken care of my problem and I was amazed at what my 59 Bassman RI sounded like!”

“The Squeal Killer really helps me get the most out of my 59 Bandmaster-I can finally hear myself on a loud stage! I get a natural, fat tone with the ability to to tweak my EQ at the amp like never before. I would recommend giving The Squeal Killer a shot if you play amplified harp.”

Bill Johnson
Knoxille, TN


“As I cranked up the amp it got to the baseline level at about 7 with no feedback, and I was able to crank it to 9 before it started barely tipping in to feedback. The amp was substantially louder than it had been on 5 with no pedals and the sound was more natural.” – (comparison to the Kinder AFB+)

“The Squeal killer is by far my favorite feedback fighter and I’ve owned all of them. With The Squeal killer, I can be heard at last, without tone coloration-in fact my amp sounds better than ever. The enthusiastic audience response is the real proof – get one!.

“Hi Jason, the SK arrived on Tuesday and I gigged with it on Saturday and it was brilliant. The extra volume boost meant I could easily compete with the rest of the band ( during sound check i was even asked to turn down! ) and i was able to add more treble so my harp really cut through. I have tried the lone wolf anti feedback pedal and the kinder and the SK beats them both, so easy to use and it doesn’t mess with your tone. The SK has allowed me to use my Bassman RI to its full potential and I’m very impressed.”

“Received The Squeal Killer Tues. Put it through a Harp Gear 35 at the Wed. Jam and through a Mission 50w 3×10 at a Thurs jam. Both great sounding amps on there own but with The SK more explosive and of course it’s main purpose no feedback at much louder levels.

 

The additional benefit with the 50w Mission was I was able to use the 3 way mic boost at a higher volume than ever before. I normally could not make use of this unless at a lower volume.

The guitar player who run’s the jam here in Joliet actually turned around, walked over, and looked at my amp!”

Mics used:

  • Greg Heumann Custom w/Shure cm

“Hey man, played through mine today. Very good. In short what I found was anti-feedback qualities about the same as the Kinder with some slight variation depending on mic used. No noticeable effect on tone, or none I could pick up. I was playing through a stock Bassman RI with the SS Rectifier. I got up to 8 before it just started to ring. I could tame that down by some adjustments on the amp but it was very loud. Basically I don’t need the Kinder now. It is a good pedal but do not like the tone changes. The SK is so simple. It is the $*%& man ! I will tell my harp playin buddies about it. I love it Jason!”

“I’ve tested the SK and found it to work as advertised. A really simple and effective way to tame an unruly amp”

“Pedal worked well. I used The Squeal Killer for the first time last night with a Sonny Jr. 1 4×8 amp. This amp has never had much headroom when playing with a band. Now with this pedal – amp on 8, mic turned halfway and I have the headroom I was lacking.

The amp sounded glorious.”

Hey Ron used the Squeal Killer at two gigs this weekend. Both times I played through the SK to my delay to the Harp Attack and into the PA. Worked like a charm. Great tone and no feedback! I was playing in front of the PA speakers and even pointed my mic right at them, no feedback! Lenny C


Well I got mine today. Played it through a stock bassman ri. It does cut down on feedback. I tried plugging in at the same setting without the SK and couldnt get anywhere near half the volume. Settings changed with each mic I used but still provided good anti-feedback. I did notice with both pedals at some point you will get feedback but at very loud levels. The anti-feedback qualities are about the same as the Kinder. What I like about the SK is it's simplicity ( no knobs ) and very little if any tone change. What you play into it is what you get out. I dont like having to plug in the adaptor which can be a bit of a pain on stage but can be taken care of. Im glad I got the SK. Worth the $$. Rick Parrish

I purchased a Squeal Killer to tame down my vintage 1962 all tube PA head. The head has been reworked for harp but I still couldn't use it on some gigs. The Squeal Killer has just about doubled my volume output and the tone is the same from what I can tell. Great product...Thanks soooo much! TS


I have both the Kinder and the Squeal Killer. They both work well, but are completely different animals. If i could only have one it would be the Squeal Killer. Chuck

"For players that love to play balls-to-the-wall loud and need to get every bit of crunch and volume out of a unmodified amp... plug in the SK... slap in a bit of delay to take the rough edges off... and you have yourself a huge sound."

�WOW! I'm not easily impressed but the Squeal killer allowed me to get more volume than I have ever been able to achieve with tube substitution. The SK also allowed me to change the settings on the amp much more. Less Bass,a little more treble and if I wanted a real compressed sound I could push the mids. The best thing is that all the other feedback pedals changed my tone. The SK had no effect at all on the tone. Understand I don't like add-ons but I will be using the Squeal Killer on my gigs with the Bassman for sure. My tone took a huge leap (and I've been told by many players that I have big, full tone already). This is way cool and so easy to use. You have changed my approach to playing.

Just wanted to pass along my $0.02 on the Squeal Killer after receiving mine and playing about 1.5 hours on it between yesterday and today in my living room. The very quick summary is that I�m really happy with the sound it delivers through my Bassman RI, and it allows me to dial in optimal tone without feedback. Even before I got the SK, I was satisfied with the tone and volume I was getting from my Bassman RI; however, at times, I had to be extra careful with cupping technique, amp positioning, body positioning in certain situations to avoid the occasional feedback issue. Not really a problem with the amp, but it messed with my head a little bit when I would have preferred to just concentrate on the groove and playing. The SK lets me tweak the amp settings for optimum tone without worrying about feedback, so I can relax and focus my full attention on just playing instead of having feedback concerns rattling around in the back of my mind. With the SK, I am running the volume just a tad higher than I did before (although with the SK, it is capable of higher volumes without feeding back), and the tone is really in the sweet spot with no feedback issues. To my ears, the SK is pretty transparent at medium to medium-high volumes, then becomes more noticeable when you push the volume knob up approaching the threshold of feedback. Although it does not have a major effect on tone at moderate volumes, to the extent that I can hear the difference, I actually enjoy the change in sound that the SK creates; it seems to add a bit of punch to the attack of each note and thickens up the overall sound. I am heading out to a local blues jam this Tuesday night, so I�ll have a better idea of its capabilities after that. Cheers, Rusty

Be heard!

No anti feed back unit is perfect but this is as close as you can get. I have tried the others and they all act differently. The squeal killer works like magic. Like it isn't even there. No buttons, just plug and play, and I mean play!!! You will be heard! Finally. And you won't have to blow out your harps trying to hear yourself on stage. I find myself actually playing softer with more dynamics as opposed to just playing so darn hard just to barely hear what I was doing. Now my time on stage is an utter joy, knowing that I can cut through any time I like. That is the power guitar players enjoy all the time. Here is what I really notice using the Squeal Killer... The moment the other players can actually here the darn harp, they lower their volume, hmm. Like speaking up in a conversation when you want to say something. I set mine up in the back of the amp so it is always there. I just plug my amp into the wall and I am playing harmonica not pedals. Also cheaper than other models out there. YMMV
