Donner Octave Guitar Pedal, Harmonic Square Digital Octave Mini Pedal Pitch Shifter 7 Shift Types 3 Tone Modes Sharp Detune Flat True Bypass

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.

Donner’s pedal reviews are all mixed together! This one is for the "Harmonic Square" pitch shifter. To start, the main description is misleading. It is much more than an octave effect, offering many other intervals. It also has microshift/chorus effects. When I read the deeper description, the pedal sounded like the exact feature set I had been looking for among other octaver/pitch shifter products. Nothing does exactly what this does, specifically in this micro form factor, it is really amazing how much the Donner packs in. It was not much of a risk given Amazon’s return policy, so I went for it. I’ve played a lot of pedals in this category, and the Donner holds it’s own on sound and tracking extremely well. Also very low noise. And all for this price?? It’s really a steal. It kind of puts a lot of other name brand and boutique pedals in its class to shame. Not a sexy as a package as the boutique builders, but who cares when it’s this good on price and features? Time will tell with long term reliability, but the build quality seems great.

I've been performing with this one for half a year, now, and it has become a fundamental part of my equipment, more so than I expected. I wouldn't even think of going anywhere without it, now. Originally, I got it to fill in bass when the bass guitarist didn't show up. Now, I use it mainly for chorus, which it does quite well. Here's a breakdown of the functions, and how I see them: The +/-2,3,4,5 functions are gimmicks. Unless you're playing an avant garde piece over a chromatic scale, this will never work. Having a harmony tone exactly one set number of steps from the played note can't follow any particular scale, so it's a recipe for failure. This is not a product defect. It's just a fact of music theory. The sharp function may be another matter. My thought was that moving the pitch in whole octaves should be fail-safe. If the note you play is correct, then one octave removed should also be correct. Setting it to -1 octave (flat) works nicely. Setting it to -2 octave (flat) works well enough, but it's too low to be practical, unless I'm riffing on the high E, which I never do for an entire song, so I don't use it. Incidentally, flatting the note means having to play differently, also. -1 flat octave works great with power chords, making them more menacing, especially with all-neck pickups and high distortion, and it also works well for imitating a bass guitar or doing a solo resembling a twelve-string guitar. However, it means needing to play more simply, because it doubles the likelihood of muddiness. However, while the flat octave functions work as expected, the sharp octaves bite the dust. Single notes sound like comic effects, like a drunk duck that inhales helium. They're also delayed a fraction of a second. If an entire chord is strummed with a +1 sharp octave setting it sounds somewhat like a pipe organ, and actually can do a pretty good imitation of phantom of the opera. This, probably, could be listed as an item of bad design, but I didn't get it for this function, so I don't care too much. Lastly, but not least, the detune function gives three different intensities of chorus, described as +10 cents through +30 cents detune in the clockwise direction, and their negative counterparts in the counter-clockwise direction. For the record, detune means the same thing as chorus. Also, the negative versions sound exactly like the positive versions to the human ear. Of these settings, only the most subtle sounds good. In fact, it sounds great. I love it. The other two get a little weird. A power chord on the mild detune sounds richer and fuller. Dirty signal gets the edge smoothed off of it a little, making it more palatable to the average (non-heavy metal) ear. It shimmers well. So, the short of it is that most of the functions are junk, but it has two great features that redeem it. It's not like I want to be crouching down and changing the settings during a performance, so all I really need is one great setting that I can leave it on, and punch it on or off at will. I'm quite happy with it. I only dock one star because I feel that the octave sharp function really could have worked better.

This is the second pedal I have bought from Donner. The first was their looper which is very nice. This pedal is called a pitch shifter but it's much more than that. This will add 2nds, 4ths, 5ths, 7ths or one octave or two octaves either sharp or flat to your original signal. It has a level control for wet and another for dry signal. It is made out of metal and is built like a tank. The are very few if any artifacts added by the pedal and it is true bypass when switched off and is silent when using it (no background noise). I love this pedal and mainly use it for adding 5ths to lead lines. It is generally for single notes and not for chords. It is also a handy way to turn your 6 string electric into a bass just by setting the switch to flat and the knob to one octave. I am very impressed by these Donner pedals and really like the mini form factor. I would recommend this pedal to anyone looking for this type of effect. The price is right, they provide fast shipping and these pedals are basically indestructible. Get one.

As said in title, this is a decent pedal with an okay effect for the money - what i could not get past was the immediate loud aggressive hiss it introduced *by itself* with my bass. It's a darn shame too, because it actually has a nice effect when used in its 1 or 2 octave above effect. 2 octaves was very reminiscent of horns! Sadly, this would be sitting amongst high-end rack mount effects and chained with high end source audio pedals, and i just can't have such a low-end item introducing so much noise. Yeah, i could buy a noise gate, but then the price of the pedal is doubled and a single ledal shouldn't require a 2nd to offset poor quality noisy engineering. Returned it for a refund. This would be a good fit for a teen on a budget, but for a serious older musician this isn't what I'm looking for. *Note, was using a brand-new donner branded power supply for it.

What a fun and functional pedal! My favorite is to do 1 octive (mostly down) and get that Wes Montgomery jazz solo feel... or play with friends and be able to be the bass player on songs that scream for a bass instead of a 2nd guitar (and not have to bring more equipment). It is super versatile going up or down by 2nd, 3, 4, 5, 7 and octave intervals. Even the "cents" offset can thicken and give a bit of a chorus feel. Also, Donner customer service gets an A+. My footswitch was noticeably nosier in switching than my other pedals, including other Donner pedals, so I wrote them and they replaced it very quickly. They are such a great value I have added the noise gate, compressor, and graphic EQ to my board. I have higher priced pedals (Fulltone, Vox, VHT) and these hold their own on my board. At these prices and quality (and small form-factor) it makes it easy to explore... Good job Donner!

Did not work, just hissing noise when you engage! Good thing I checked it right away because sometimes I get busy and not test a pedal!

The Donner Harmonic Pedal is a winner, especially at this price. Though the basic pedal function is a pitch shifting pedal meaning depending on where you set the middle knob and the toggle switch you can get your standard pitch plus an octave above or below in addition semitones above or below. The wet signal (octave) level can be adjusted as well as the dry guitar signal. This pedal is what I would describe as application specific in other words used on its own it might be too dissonant for most situations. In this demo/review I have attempted to show some possible uses but certainly not all of how it could be utilized. Tone being a goal of most guitarists; in that our basic tonal personality can easily be hijacked by a unusual sounding pedal, blending dissonance with your basic sound (tone) can add a dimension to your musical impact. This is not a substitute for lower register or higher register instruments but can be used effectively by carefully blending the sounds into your own take on something or just be an inspiration to create around the new found sounds. The video accompanying this review seeks to show you just some of the possibilities. Lastly thanks to Shaggy's in Cat City, to RV Velasco for his technical genius and moral support ,to our dogs for adding interest and lastly to Donner for making this all possible.

Me ha sorprendido la calidad del sonido y las diferentes posibilidades del pedal. Con wet al100% y dry al 0 situando el control en 1 octava y el interruptor en flat por fin he conseguido que mi guitarra suene como un bajo. También se puede armar una guitarra de 12 cuerdas (wet 50%, dry 100%, control 1 octava, interruptor sharp). Y éstas son solo dos de las múltiples posibilidades de configuración... Muy contento con mi compra

It is small and has surprisingly good sound. However I think it has to long delay time for the wet sound. But if you mix it with the dry sound you can get pretty cool sounds. To small knobs. But it feels like quality and a it comes with a manual and vey good packaging. It has a pretty high current consumption compare to other mini pedals.

【非常に大きなプラス】 ①サイズ：非常に小さくて便利。 ②インプット・アウトプットケーブルのの高さが違うので、 エフェクターボードでスペースの最適化。 ③電源：9Vなので、パワーサプライと安全に使える。 ④音：SQUAREの音だという前提で、変な音出さず、バランスが良い音である。 ⑤設定：±2 OCTの設定あり。 ・音源 + OCT の音をバランスのは可能。 【マイナス】（使い方次第） ・+1と+2 OCTが同時に使えない。

Sono tre effetti in uno; ottime possibili regolazioni, nessun ronzio.. Consigliatissimo!

Pretty good, it can produce a chorus pedal like sound but it doesn't go to eflat(half stel down)
