Great pedal and a great price
Kirk H.
Overall, I really like this pedal except that it introduces some background hiss that can be a problem, especially when used with other pedals in the signal chain. What like is that it does a very accurate shift with many choices of intervals and other than the hiss, the tone is very good.
Ben S.
Love the wide range of sounds available on this one little pedal.
Johnny C.
Excellent, great sounding pedal! Highly recommended!!!
Russ S.
The full “12” string sound is what I want. Now I have it! Plus just a few tweaks gets a real unique sound. I also use the looper. OMG the best thing for me but my drummer is not too happy. I’ll use the looper and pedal to build my solo shows. Great products. I want to buy another looper/drummer pedal so I have back up. I’m having some issues with the on line pairing however.

I bought two Harmonic Square 7 octave pedals for my bass guitar. I wanted to daisy chain the pedals so to have and octave and a 5th above to mimic a guitar power chord. Unfortunately, the pedals have latency and do not track well on bass. Also, there is sometimes a slight metallic sound on the lower notes that I believe is caused by tracking glitches. These pedals may work fine on a six string guitar, I don't know. Also, Donner Customer Service has been reluctant to issue a refund. Something to also note...
Robert N.
Bloody Great Petal love the tone even makes my acoustic/ electric sound fantastic well worth the scratch...

What a terrific little pedal! This stomp box offers a LOT of value for the price- from being able to emulate dual leads, to adding richness to chording and solos with the 'octavizer'. This effect pedal has a lot of the same qualities of an old pedal I had in the '80's (which was WAY clunkier with many levers and knobs). By contrast, this box is very economical with the use of space and the layout of the knobs- very intuitive and easy to master. This is my second Donner pedal (I also have the tuner mini-pedal), and I would definitely stand by the quality of these products!
Darshan M.
This little thing is pretty cool! You just have to know what your trying to do with it or you can get some pretty strange and awful sounds if you are just turning knobs as if it were a drive or phaser. It has many different applications and it’s NOT just for guitar! Try it on bass and definitely synths! Octave up or down and 5th are useful for harmonies, the detune can fatten up an analog synth really nicely. And if you turn the dry all the way down you can use it to change your tuning sort of like a capo but for anything… I wouldn’t put it on the necessities list but it’s a cool extra , and it works nicely. The tracking is good even on chords and has just the slightest amount of noticeable latency.

I've owned a couple of synth guitars (as well as a few keyboard synths) and while synth guitars might be more versatile than this pedal, there can be issues with latency or random pitch glitches or even just settling on a useful tone after lots of fussing around. This little box is magic! Square waves are one of the options with analog synths (others being triangle or sine waves) so this is in fact a mini-synth tone generator. With the switch up it's additive and I can find a searing lead synth tone; with the switch down it's subtractive and can even go low enough to emulate a bass. The middle position is a good chorus, the only drawback there a lack of speed control. Granted these are all preset options, so there's little to adjust except for the variations on the main knob and balancing the original guitar tone with the effect, but bang for buck, this is one of the most fun pedals I've tried in a long time!
Robert R.
Price point is unheard of in the pedal world. What you get in this tiny pedal is huge in sound. It really fattens up your tone on either the chorus setting or with pitch shift with some tweaking. Great for soloing. One of the best tracking pitch shifters I've ever used. Great job Donner !
Allen G.
Best bang for buck pedal to add harmonics and octaves to your tone. Great value. Strong build. Swift tracking. Small size. Winner!
Kevin H.
Awesome pedal ! All of your pedals and products are amazing . Using them in my band @first_class_creeps
Scott S.
solid little harmonizer pedal--tracks well, and sounds decent.
Customer
I really enjoy using the Donner Octave box. You get a wide range of settings that other octave boxes do not offer, also there is not the signal loss that other boxes are know for. Donber: Excellent products at a very fair price. Thanks
Lester G.
I will be more happy when you send my pedal back to me, the one that came back to you !
Jesse R.
this unit is a bit unique to get a good tone... just a lot of funkyness...
Ian B.
Works well with my basses. being able to pitch shift up and down is great (though not at the same time). The octave 1 tracks really well, octave 2 down tracks ok, sometimes struggles on the lower notes, but so did my Boss OC-2.
The other detuning options really add some interesting options to the sound, and being able to mix as much as you want with the wet and dry dials is great.
Peter R.
Very cool, I use it to sound like a bass player is doubling the guitar
Brad M.
I use pitch shifters a lot with my basses to add texture, octave up and two octave up mainly but the fifth and fourth up are usable too. This pedal does quite nicely and the added bonus is the detune. I find the tracking and sound to be good and pleasant on single notes in all ranges, the HS follows nuances like bends well and will also harmonize harmonics and chords up on the neck. This is the second pedal from Donner and I am quite pleased with the performance and sound of both of them.
toni w.
first i say, hail donner. they are the kings of affordable effects. i have a bunch and they are all pro quality in sound, looks, and unique effects. these arent simple clones. they all have there own personality and sounds. someone at donner wants to be special and not just another freakin clone! this pedal here the harmonic square has changed neverything for me. it is an all inportant and versatile tool for any guitarist. first off, as usual........top of the line build! they care! this pedal was done right. you cant believe all the different functions and sounds that this pedal provides. ive played for 35 yrs. and have never had an octave till now. holy cow, you can find a thousand sounds with this thing. stack with any other pedals and listen to the magic flow. nothing ive tried with it sounded lame. if your into ambiant, doom metal, pop, country.....i dont care. it allows you to dip into all genres. im using it for ambient rythm and doom metal and couldnt be more satisfied. like i now say...........donner is king. these pedals are solid, silent, snazzy looking and each one has alittle sumn sumn that makes them stand out. dont wait.............get ya one, before there gone 4-ever.,,,,,,,,,,,,,,,,,,,,,,,,,thank you all who labor at donner. i appreciate your hard work , and attention to detail.
bobbie s.
This octave pedal is FAR superior to another octave pedal I have which cost 5 times as much. It is totally noiseless. Tones are true.
Allen G.
Of hundreds of pedals I've played, this little Donner Harmonic Square stands out as a "best bang for the buck" because it tracks like a champ and has many, many useful overtones to add harmonics upward and downward from one's original signal.
Marc E.
I bought the Donner Harmonic Pitch Shifter pedal mainly to drop the tuning down from E standard to C and B standard, without having to change strings.
The pedal has volume control for "dry" and "wet" output. Dry is your guitar's pitch, wet is the altered pitch output from the pedal. Turning down the dry allows for shifting the pitch up or down in harmonic increments.
Having both wet and dry knobs turned up has its uses, but limited in practicality to octaves, fourths and fifths. The detuning mode has interesting results. I use it mainly to alter the pitch of A 440 Hz to A 455 Hz.
The Donner pedal works really well with Ubisoft's Rocksmith 2014. No extra noise, no delay, and the true bypass feature is no lie.
The pedal is a nice size and lightweight. The body is metal, and of sturdy construction. All the knobs, dials and buttons are standard parts, and can be replaced if worn or damaged after long use.
In summary, this is a great pedal for its price. The Donner company is an Amazon partner, so you have the option of ordering from Amazon, or direct from the Donner website. Ordering from the website gives you access to better prices and deals, and their rewards and affiliate program.

Hook this pitch shifter to a fuzz pedal and...yesssss!
Phillip C.
This pedal is great. Quiet, solid, metal, mini pedal. I wanted something to let me loop some bass sounds without buying another guitar. 1 and 2 octave drops sound believable and works great for what I needed.
The controls let you take away the guitar sound entirely. Great buy.
Mike E.
I have two Donner pedals & two more on the way! They are a nice addition to my setup and the compact size definitely helps with my space limitations. The pedals work very well and do not produce any noise in my chain.
Devin M.
Works great and as advertised for a great price, small and compact with a professional sound. 10/10 would buy again.
Milton H.
I look for guitar pedals and accessories on line, almost daily. As seen here I buy Donner pedals very often. I keep coming back to DONNER products because the quality and pricing allow me to explore within my budget! My lastest add is shown in the middle, the Donner Harmonic Square. Really like the variety this pedal gives and stacks well with my other pedals. Try them, loads of options!
Ken W.
i have been looking for a way to laydown a bass line to accompany my my music tracks when i came across the Donner Digital Octave Guitar Effect Pedal. After watching/reading reviews on different octave pedals i purchased the Donner octave pedal and couldn't be more pleased with the price, quality and operation. my plan was to find an easy and economical way to laydown bass lines, but now i'm using the rest of the harmonic tones more than the bass octave mode: it's a very versatile tool for making music. i recommend Donner pedals for a musician that appreciates quality, price and function.
Robert S.
I love this little pedal! Most importantly the sound is great. It tracks well and has multiple functions that are actually useable. I like to use the octave up sound as well as the octave down. I wasn’t expecting to get much use out of the 4th up and 5th up sound, but it’s turned out to be a very interesting sound which has inspired new compositions that I would not have otherwise come up with.
Beyond that, the build quality seems very good. It’s housed in a metal enclosure.
The price was the cherry on top. Very affordable, especially since I happened to get it on sale. And a good sale at that, not just a few dollars off but a good percentage off.
I’ll definitely be checking here before making any future purchases.
Red L.
Both of my items arrived quickly & surpassed my expectations. & when you factor in the low prices they just can’t be beat!
Shawn S.
Product works as advertised and small size let’s me fit more stuff on my board
Caden F.
I never received the product. The item seems to be lost in transit and the two (don't laugh) delivery companies say its the others fault. The shipper will not refund my money. 100% dissatisfied at the moment.
dean b.
This unit works great and is set up to do up octaves and down octaves . I love it.
Dan H.
I really recommend this pedal. It works, and the sound comes through super clean and if you were to be just hearing it you wouldn't be able to differentiate between the pedal effect and an authentic bass. Has some super fun harmonies you can play with by changing the 5ths and 7ths settings sharp or flat, with the detune adding an odd chorus effect that shouldn't work, but does.
Can add a lot of flavour to your playing, and if you don't want to learn bass, well, you don't have to, because guitar and octave pedal.
Richard J.
Great pedal for the price, makes clean, fun tones.
Matthew G.
a lot of options in one box
Fun for bass and keys too
+1 or +2 high and low octaves, 5ths 7ths are very usable and then there are fun dissonant harmony settings too
Detune mode makes a great sounding chorus
I put mine after my arturia micro brute mono synth before a fuzz and im having lots of fun, honestly kind of want to buy a spare, esp bc it's so affordable!
Mackenzie
If you're considering buying a budget octave pedal I would just go ahead try it out.
It's an extremely solid and affordable pitch shifter and as of writing this review its on sale so yeah, hop on it! If you are experimenting this a really useful tool to try and make new sounds like thick rock riffs and meaty synth like tones, especially when used with a fuzz or metal boost pedal. In particular this set to octave down plus a Donner Fuzz Seeker makes it feel like I'm Zeus holding lighting in my hands!
The important point is that it has pretty much all the same features as comparable models and does those things very well for the price. The tracking felt a bit slow at first because I use SRV style left hand muting so I can run the pick through all the strings but only sounds the ones I'm fretting and getting extra scrape off the ones I'm muting. The extra noise was slowing down the pitch tracking so a small adjustment later and now I find that it's really quite close to real time and that I don't notice any delay after 2 or 3 minutes of rippin'.
James R.
Sounds great. Makes a loud humming sound when on the sharp function.
Frank L.
Amazing product
Huge palette of tonalities to play with.
John E.
You should include a charging unit with this pedal ... It has to have the correct one , not just any 9v charger ... Or at least show it as an option when the customer orders the pedal
Eugene W.
I'm not a pedal guy but bought this on a lark - plugged it in and what fun it is. Besides just playing with it I use it when I go thru the daily scale practice - they are no longer boring - maybe a looper next.
Brian C.
I wish your site had mentioned this was a Monophonic pedal. As such, I can't use it to down-tune my guitar and play chords. Worse still, you label it as a bass pedal, but it doesn't work properly below low A, so I cant use it with my bass. And it really changes the tone of the sound, and adds a lot of noise if you follow it with high-gain pedals. I am really disappointed.
Roger K.
I was excited to give this pedal a try. When I tried it for the first time; it was everything I expected. The shipment arrived in a timely manner. I would suggest this product to any guitar player. Good job!
John P.
The Donner Harmonic Square 7 Octave pedal is versatile, transparent, and noise-free. It exceeds my expectations in every regard. Every Donner pedal I own (this is my 6th) has been very quiet, both in by-pass and active modes. This one is no exception. I still do not need a noise gate at the end of my effects chain. What impressed me most about the pedal is the natural harmony it produces. I knew that it would be versatile with the 7 modes as well as the flat/sharp toggle switch. But I actually expected the "wet" harmonic sound to be artificial and tinny, as well as slightly delayed and phased. Much to my pleasant surprise, the "wet" harmonic comes out as natural as the "dry" note going into the pedal. The "dry" and "wet" levels allow me to fine-tune the output for precision. My audience (even the seasoned musicians) could not tell which note I was playing and which note the pedal was producing to harmonize. Being the lone guitarist in the band, I can now play leads with a touch of harmony when needed to add that little bit of extra richness at precise moments in a song.
Daniel W.
I here's a shot of my home made pedal board with my new additions the Deluxe tuner and the Harmonic Square 7. I can't believe the flexibility of the Sq7!!! It can add a bass line under your lead, harmonic runs, and can make your 6 string sound like a Rick 12 string. I have just experimented a little with it but I can safely say that it is the best bargain I've seen for the money. Try one and you will love it.
Joe D.
These pedals are built real nice and sound even better
mike n.
Great guitar effect....GREAT price......
Jacob B.
The Bees Knees! Tracks super well. Low octave is clear and easy for looping bass parts. The detune setting even has some great chorus sounds.
Keith H.
I'm a bass player and used to the boss oc-2, for the price this pedal is great and adds a nice fun tone and the settings are a lil different than most octave pedals I've used but its a great pedal for the price and how small it is.
Alain T.
Very Nice pedal !!!!!!!
Alain D.
seems to be noizy, will try some tune-up and hope will be better.
Allen G.
Best dollar you can spend to dial in tons of overtones from sub bass to hyper harp. Tracks like a pro for half the dough. Small box tucks in nicely with other pedals. Really quite magical that so much can be done with just one little pedal. Donner got this one done really, really well.
Terry H.
Well built, sounds Great. Love the octave and, harmony pitch shift. Almost a 12 string sound.
Nick C.
The best octave pedal out there by far! So many other sounds as well. Tracking is phenomenal and love the wet and dry blend knobs too.. Built string and smart. Thank you!!!! Great ideas and sounds
Gregory J.
Makes my Sub 37 sound even more spectacular and slick when I mix equal part wet/dry +/-7 out of phase, makes a really big incredible detuned chorus sound Beyond impressed.
Jesco H.
Nice and solid pedal with many functions in the pitch area. Useful with many sounds in the clean or distortion section. I like it to round up my special guitar sounds. Thank you donner.
Laercio M.
The pedal fulfills what it promises. Good quality, it's already my fourth Donner pedal. You can use it as a drop, very cool.
G***r
People! Whosoever the Not buys is itself fault… Super Device… have Nen cute Deep Purple sound so;)
f.miguel
Works as expect
Nice pedal, stronger than I expected, and good sound.
B.Leo
Sounds Great!
Tracks really well, sounds fantastic. My only complaint (and this is really picky and isn't a problem in most applications) is that there's a few milliseconds of silence if the effect is on and you start switching modes. Other than that, it's perfect and extremely versatile.
Rodrigo
Great for band rehearsing
Really good for practicing in different tunings!
Carles
Sounds great
Very hardy pedal, It's very well built. The sound is good and it does not make any noise. Small but great one!
Arno
Royal little thing..
Very very fast shipping: 8 days from China to France and pedal is more for what i espected!very well built, from octave to kind of chorusing mouvement, dry and wet pots efficient and all of that in respect of thé initial sound.one thing: in thé package, only thé up side is protected with foam, why not down?Conclusion:for the money, it's Royal!!
