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.

Overall great buy! Checked a few videos online before buying This is a great pedal. I don't usually do reviews online but this one seems it's worth it. Pros: -works exactly how it's supposed to -tracks your playing perfectly (I do a lot of really fast picking on solos and just shredding in general) -Works a beautiful Chorus pedal in the middle mode -you can double yourself or play harmony without having to use a looper to re record what u just played, lot of fun -You could even use this pedal as a capo to change the key mid song when you set the dry signal to 0 and the wet to max The octave down, 2 octaves down, and 5ths are mainly what I use it for so far. The 3rds 4ths 5ths 7ths both up and down also sound awesome (keep in mind these intervals will only sound great depending on the keys and progressions you're playing) Con: -the "1 octave up" and "2 octaves up" don't sound that great compared to the rest of the functions. They're true to pitch but don't really sound like it's really the guitar's true tone. (Easiest way I could explain it) *But, they still sound good when you lower their volume in the mix **One thing I wish this pedal could do is integrate a footswitch to change between intervals and modes and not having to bend down and change it before a next section in the song you're playing! But I reccomend this!

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.

I was seriously impressed with my new Octave guitar pedal. I couldn't stop grinning from all of the cool sounds that I heard when I initially plugged in. All I really wanted it for was just for the drop tuning but it does so much more than just drop tuning and harmonizing. First: I wasn't expecting the build quality to be so impressive and Second: I an just blown away with the range of the sounds and the quality of the signal. I'm seriously gushing because I was going to buy a Digetech Whammy pedal and then I saw the Donner pedal. I was thinking if it sucks Ill just return it. Nope this isn't going anywhere. So if you don't need the Whammy wha wha type foot controller, I highly recommend the Donner Octave Pedal VS the nearly $400 Digitech which has way too many gimmicky options that you will never even use.to be clear, I have nothing to do with Amazon or Donner and I hardly ever write reviews. But for this purchase, I just had too. Get it and enjoy.

The Harmonic Square generally does what it claims but will likely have limited use for most. It's very sensitive to where it's placed in your signal chain. Took me some experimenting to find a placement that didn't introduce an odd pulsing/clicking in sharp mode and a loud droning noise in flat mode. Once I found the right spot, it was mostly functional. It's definitely better at handling single notes. Lots of weird effects if you play full chords. Dropping an octave to try out some bass line ideas is also pretty easy and passable in a practice setting. Not sure I'd ever use it for recording or gigging. For the price, it's an OK introduction to pitch shifting pedals to allow you to try things out without spending a ton of money.

I wanted a pedal that could make my guitar sound like a bass so I can create complete songs on my looper. For the price, this thing does a great job! I turned the wet knob on the pedal all the way up, the dry knob all the way down, and I turned the octave down one step (two steps down was too much). On my guitar, I used the neck pickup and turned the tone knob down to about 1-2. On my amp, I set the bass at 7 and treble at 4. What came out was a nice fat bass sound that didn’t sound muddy. I looped in a bass line for a few riffs I had recorded earlier on my looper and wallah! For $50, I can’t be happier!

Weepy & wanky.... If you want a cheap pedal, just buy a Berhinger. Otherwise, get something name brand. Makes late 90s plastic danelectro pedals seem like earthquaker devices

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。

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

Não regula semitons...
