Compact, inexpensive, and sounds great.
For the cost I cannot find anything to complain about with this pedal. The Donner Distortion pedal allows me to produce a wide range of distortions, from a relatively mild, overdrive tone, to hair metal. Adjusting the tone and volume using the knobs is simple, and the noise level is not overwhelming, and disappears completely when using a noise gate. I've been practicing and gigging with this pedal and it has held up great so far. It is powered by a standard, 12v power supply (not included) If you're looking for a compact, inexpensive, distortion pedal for your board, I highly recommend this one, it does a nice job at a great price.

Two Harmonic Squares together are AMAZING!!!
So I ended up with 2 Harmonic Square Pedals. Wanting to gift one to a friend, I plugged them both in at the same time, you know... keep the 'good one' hehe. WOW!!!!!! I cannot describe how nice they sound together -running one into another. Used separately they work very well and do what they should (including a killer chorus in the 'detune' setting) but together they sound so rich, deep, full, shimmery and expensive. With both of these on at the same time there is near endless settings just flipping the switch and turning the pitch knob. Easily sounds like a $450 effect. Run these into a tad of reverb/delay and it's absolutely amazing ambient heaven. It could be one of the coolest pedal combo's for shimmer/pitch/chorus/octaving/doubling... SO GLAD I ACCIDENTLY TRIED THIS. So in short, I'm buying my buddy a new one.

Sounds AWESOME!
I really enjoyed using the looper pedal by Donner. Once again this brand delivers an excellent product at an extremely low price point! The controls are very easy to use, though I did notice a slight difference in sound quality when being played back through my amp, not too bad though. I removed a star because I noticed another persons pre recordings were saved to the device but that’s hardly a complaint. I would definitely buy again!

Worth it
Surpassed my expectations. I was picking this up just so I could use it for down tuning, turns out the dry/wet knobs give uou some amazing results when it comes to crazy effects. Well worth the low price!

Great looper pedal
Fantastic Looper for the Price! I’ve been using the Donner Looper Pedal for a few weeks now, and I’m honestly impressed. It offers 90 minutes of total recording time across three tracks, which makes it super easy to layer different parts and experiment creatively. The sound quality is clean with no noticeable loss or noise, and the unlimited overdubs plus undo/redo options make recording mistakes no big deal. Switching between tracks is seamless, and it feels sturdy and well-built for something at this price point. Whether you’re a beginner practicing timing or a performer building full live loops, this pedal delivers way more than you’d expect. Highly recommend it!

Literally 6 broken pedals in a row — strange recurring chirping/beeping pedals
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.

Reçu et testé plusieurs heures avec divers effets ; déjà arrive bien protégé dans sa boîte , la couleur vert anglais métallisé change des éternelles noir , rouge, blanc. Peu de paramètres mais qualitatifs et suffisants : ne colore pas le son qu`il reçoit ; quel que soit le mode ( hard ou soft ) la chute naturelle des notes est respectée. Le jeu très rapide et incisif , ou lourd et appuyé ne lui posent pas de problèmes. Je le place au niveau d`un noise gate 4 à 5 fois plus couteux. Pas de boucle pour les effets bruyants , mais peu importe : ceux-ci avant le noise killer les autres après. Dans mon home-studio j`utilise un noise gate / expandeur en rack plus complet bien sur , mais qui demande beaucoup de temps pour être calibré au vu des paramètres , sans parler du prix. Je destine celui-ci à un usage nomade avec mon petit ampli de travail et quelques pédales , mais l`on peut sans craintes l`utiliser pour une prise de son. J`avais déjà des patchs Donner , de qualité ( pas loin de mes EBS et MOGAMI ) ; cette marque monte en puissance ,seul un certain snobisme peut la reléguer en 3eme choix .
