Exactly what I was hoping for at a price point that didn't break the bank!
This sturdy little pedal came in a nice magnetically closable box with a quick but useful owner's guide and a couple cute Donner stickers (I believe all Rock 'n Roll goodies should come with a cool sticker! ;-).I play mostly hard rock and metal (a lot of that drop tuned D, Db, C and B). I was tired of getting almost instant feedback (in my setting - a small 12x14 room with a 40watt all tube Marshall DSL40). I don't like using the amp in Triode mode (reducing and cutting the output power in half). Needless to say, there was a lot of unwanted noise (and feedback) coming out constantly and almost instantly.Most of my 'effects' pedal plug straight into the front of the amp (first - last: Tremonti Dying Machine Way, Joyo Compressor, Tube Screamer Mini, and a Fulltone OCD distortion). I've patched this Donner Noise Killer along with my EarthQuacker Dispatch Master Delay/Reverb and volume attenuator pedals through the back FX Loop of the amp to get the most noise reduction without affecting the tone or the effects of the other pedals (besides which, this is a True Bypass pedal).As mentioned above, I use a JHS Little Black Amp Box 'Passive amp Attenuator' to cut back the overall volume output of the Marshall amp so I can turn up the Volumes to get into the sweet-spot of the amp itself without blowing my head or the roof off! Combined with the Donner Noise Killer pedal, these work perfectly to manage volumes and unwanted noises!The pedal has both a potentiometer Dial (ranges between -60 and +10db) and a Loud / Soft switch. I find it's happy place is switched into Soft mode (which Donner recommends for most playing styles in the leaflet/manual) and the Dial set just a tad below -40db. I had to play with this a bit to find the sweet spot where I still get sweet sustain and I'm able to kill the unwanted noises. As Donner designed, it's easy to adjust and I was jamming within a couple of minutes.There's just a little "pop" when stomping the the ON/OFF button that is audible through the amp. It's not terrible however. Besides, it on all the time now anyway. Not a concern...The difference in my setup/setting is like night and day concerning the ambient noise that's "killed" as well as the amount of feedback I cut out with this little guy! With it turned off, there's a definite buzzing noise coming out of the the amp. With it on, it's completely gone! With this on and set as described above, the amount of unwanted feedback is pretty much cut out while playing as well. Now there's plenty of time to palm-mute and turn down the guitar volume between songs.There maybe a better Noise Killer on the market. You might have a buy a few to find it. You'll probably be paying 3x the price as well and it'll be, more than likely, more cumbersome to dial it in.What's left to say? I'm satisfied with this well built Donner Noise Killer.Buy it! I bet it works for you they way it working for me.

5.0 out of 5 stars Bright, solid and accurate (too bright?)
Reviewed in the United States on November 13, 2020
This is a well built pedal, no question about it. The foot switch/button is smooth, positive and quiet. This is a silent pedal when not activated so it also serves as a handy mute feature for anything past the tuner.

Accuracy is spot-on in accordance with my Korg tuner (Y-splitter with the two side-by-side), the Donner matches approximately 1 cent accuracy - this is more than sufficient for ANY gigging or recording that I ever plan to do.

The bottom of the pedal includes nice rubber pads that keep the pedal in place on hard surfaces, yet they're thin enough that Velcro/hook-and-loop will protrude enough to mount to a board with Velcro without having to remove the rubber feet - while this seems like a minor thing, IMO this is huge and I wish more pedal manufacturers did this.
The case is super tough (metal) and the surface has a nice matte finish which reduces reflection and glare from bright lighting - again this seems like a minor feature but it makes a big difference in the real world and it goes to show that Donner has thought through EVERY detail of this pedal. And I have found that what is apparent on the outside is consistent with the attention to detail given to the inside.

Of course as with most pedals it does not come with a DC power supply but if you're reading pedal reviews you probably already know this :) and you probably also have a variety of workarounds. I prefer a battery clip snap connector anyway (search "Mr. Power 9V Battery Clip Converter 2.1mm 5.5mm" - they're $3ea) or just chaining another connector on my board's DC power supply, no biggie. I don't understand why some people complain about this - powering a pedal isn't complicated or expensive. In fact, I appreciate pedal manufacturers keeping prices low while allowing ME to decide how to power the thing anyway.

The ONLY potential downside is the brightness of the LED, particularly the red, it's borderline blinding (the pics don't begin to illustrate it :)) The LCD display is awesome, lots of useful indicators in there that help bring you to tune quickly but in low light conditions the red LED is overpowering; in low lighting I can't even read the display until the green LED kicks in - at which time I don't need to see the LCD display screen. I may dim it with some tape to take the bright edge off - and of course mine may be an exception but I thought I'd share just the same.
Overall this is a minor issue and doesn't take away from the awesomeness of this pedal. IMO it's worth every dime, it's WAY better built than its competitors in the price range and it performs at least as good as (if not notably better than) other tuners I have that cost 2x as much or more.

It's hard to imagine regretting this purchase, I plan to get one for each amp even though I don't have pedal boards for each amp. At this price I think everyone should have one sitting on/near every amp.

This is my 3rd Donner pedal for my pedal board (a compressor and a tuner as well). I'm not a huge FX nut so this is great addition and takes the flatness out of the sound to make the bass notes really pop! I prefer it over a fuzz or octave. Solid and durable! Great product, great price range.

Reviewed in Italy on March 8, 2024
Anche se il prezzo potrebbe far storcere il naso la scocca in metallo è solida, le manopole non sono cheap e il tutto ha un peso 'rassicurante': non sembra affatto un pedale economico. L'effetto chorus è decisamente ottimo, onestamente per questo prezzo non credo ci si possa lamentare. Probabilmente solo un utente con un po' di esperienza noterebbe la differenza con un pedale più costoso, l'ascoltatore medio non saprà nemmeno riconoscerne la differenza (o sapere cosa sia un chorus). Lo uso con il basso e quello che offre basta e avanza. Mi è piaciuta anche la confezione, ben imballata e curata (con l'aggiunta di 2 adesivi, sempre graditi). L'unica nota negativa è l'assenza di un vano pila: il pedale è alimentabile soltanto con apposito alimentatore da 9V che non viene fornito (costo medio 15 euro, con negativo al centro).
