DonnerReverb Guitar Pedal, Verb Square Digital Reverb 7 Modes Room, Hall, Church, Spring, Plate, Studio, Mod, True Bypass

Great price and solid for pedal board scenarios and being able to switch between 2 amps or having both at the same time. Works solid. No hum or static noise. Came with stickers for my home made pedal board. Great product

Excellent. I will never be without one of these Donner Noise gates. Imo it's a necessity for every kind of music. The hard noise gate is lightning fast with no weird cutoff sounds. For the price it's a no brainer.

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.

It’s an ABY pedal. It does ABY things. Plug it in, hit the switch, and boom signal goes where you want it to go. No noise, no drama, no weird tone sucking. Just works. Honestly, that’s all you can ask for in an ABY pedal, and Donner nailed it. If you need to split or switch your signal, this little box does the job perfectly.

Great pedal. You do not actually need an ac adapter for it to function. The ac adapter only runs the indicator lights. Nice that it’s so small. Doesn’t take up much space. Good ABY switch for not a lot of money.

This is the first Amazon review I am writing, and I am only doing so because the quality control of the product is so bad as was the customer service.I am a fan of Donner. I have other products by them, including pedals of this same line. But this 30 minute looper just doesn’t cut it, and considering I have bought 6 (yes… actually 6) of them it’s unacceptable. And before anyone suggests that it’s because of my power supply: I have two different Donner power supply units, each working perfectly fine with the rest of my pedals and effect boards — I also have independent power units, and none of them fix the issue.The issue is this:For one, a general white-noise ambient hiss is present. This I honestly don’t have much of a problem with. The main thing is that when it’s recording every five or so seconds a strange and harsh digital chirping/beeping sound occurs. This sound is recorded into the loop itself. Naturally, as you make various dubs, the chirping noise is compounded and compounded and the whole arrangement is quite annoyingly taken up with this recurring beeping.I originally bought 3 back in December. My mailman stuffed those one into the mailbox on a particularly rainy week and decided not to close the mailbox for whatever reason. Given, it was wrapped in plastic and all. Anyways, these pedals didn’t work. I attributed this to water condensation or something. I returned them no problem and I bought three more.Same problem. At first it was 2/3 of the second batch that didn’t work, but then they all started doing the same thing.This isn’t a problem with a particular amp. This same thing happens on my guitar amp as it does on my bass cabinet as it does through my mixer and out my PA’s.It’s not a problem of my cables. I have dozens of different quarter inches, some I got even brand new alongside this purchase, and same issue.I reached out to their support team and explained the issue and the lengths I went through to troubleshoot it myself. They asked for video proof — which is fine, though they said it needed to be less than 20mb. This is what they said exactly:“Dear Customer,Thank you for responding to our email. We hope this email finds you well.We are humbly asking for your cooperation to send us videos so that our technical team can localize what the problem. Rest assure once our team know what the main problem is we will provide suitable solution to solve your problem.Please operate it and send us a video showing the operation and explaining the problem.(Note: The video should be less than 20MB in size.).Once we receive the needed information, we'll handle this matter with the utmost care and attention to detail.Looking forward to your reply.“I said,“I filmed a video showcasing and explaining the issues, but I have no idea how it’s going to be able to only be 20mb in size.”(My 3 minute video to them shot on my iPhone amounted to 328mb)I then went on to say I can send them a google drive link, which I did.Their next email was them mechanically repeating their former email to me, saying once more after I already sent them the google drive link. This is it:“Dear customer,Thank you for reaching out to us regarding the issue you are experiencing.We sincerely apologize for the inconvenience you have experienced with our product.Could you show us the problem via video? Could you upload the video (less than 15 MB) as an attachment.Rest assure we will do our best to solve your problem”This could just be a minor mishap, bur they switched from it needing to be under 20mb to them needing it to be under 15mb — which leads me to believe it’s really not some hardline technical consideration as to why they need the video to be such a size, and they could very well just click on my public google drive link to the video as they clearly have internet access.All around upset with this product and their service. Going to go through with my second return on this same product and shop around for different loopers — I was just very excited at the prospect of having 30 minutes of loop material, as I compose very experimental and trance-like songs, and so this was in theory absolutely perfect for my purposes, especially considering the price point.

I was skeptical due to the price being so cheap but after reading reviews on it I bought it and im SO glad I did. This is the easiest and best Noise Remover I've ever used and for such an amazing price! Super impressed. And I use High gain and high gain pedals, and it still works perfectly.

This reverb pedal works fine..........if you place it in the effects loop. For me, it was unusable directly from guitar to amp. It sounded way to digital with too many artifacts in the sound, muddy. Even in the effects loop, when I play the spring reverb with distortion, I can hear a faint wobbling sound that kinda ruins it. Clean it shines. I am liking the plate reverb setting the best. Not bad for the price. For the plate reverb alone, it's worth it to me. My Marshall dsl40r has very weak built in reverb, so this is a plus compared to that.
