What People Are Saying

Tony Holiday

I've had the pleasure of playing the Squeal Killer at festivals, theaters, bars, and arenas. I have found a use for every setting.


Rob Stone

"The Squeal Killer is a dream device for any harmonica player that has ever heard the screech of feedback as they try to turn up their amp. It saves me from fighting with my amplifier or being drowned out while playing with a loud band. The Squeal Killer is light, sleek, incredibly easy to set up and use, and it basically eliminates feedback without compromising tone. It is definitely a device that I will have with me at every show."


Rick Estrin

"Attention all harp players: You can now WIN the volume war!!! Get the Squeal Killer and you'll never again be at the mercy of another guitar player!!!"


Harold “Hurricane” Tremblay

“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.

“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.”
