Review: Solid build. A lot of fun - I've have this for around two weeks now and it's a lot of fun! I've recorded a video that runs through some of the settings particularly near the end. I recorded it with my phone. My intonation is slightly out on my guitar so excuse that. Build quality is excellent, made of metal with a nice finish. The different sounds I can get out of this thing are unreal! It really does sound like an organ at times! You can adjust the amount of wet and dry signal you want and the pitch shift effortlessly with two knobs and a switch. I can see this being really handy when I want to play along with a recording which is in a different key but I don't want to detune! I have found this adds a nice flavour to my tone and helps to fill it out a bit when I'm just playing in my bedroom. It tracks nicely and there isn't a massive lag that I have noticed. Size wise it's a micro pedal so doesn't take up loads of space on my board. It's about half the size of a standard sized boss pedal. It doesn't take batteries so needs a 9v input but this keeps its size and weight down which I'm all for. All on all this is a great piece of kit at a really affordable price when compared against other manufacturers. I can't justify paying a premium when this is solidly built and does exactly what it says it will. With the money I saved I will definately be buying more donner products to add to those I've already bought. Never been dissapointed yet with them!
Review: 32ms Delay Does Not Ruin A Good Pedal - The Donner Harmonic Square is a wonderful little beast, very robustly made and very efficient at what it does - pitch shifting! The unit has four controls and a clicky stomp button. There are two very small rotary knobs to control the mix of the dry and wet signals. This works exactly as expected, allowing you to mix from completely dry through to completely pitch shifted. A selector switch allows you to choose between sharp, detune or flat. The larger rotary knob allows you to select one of seven static pitch shift positions. There is no option to slide pitches between positions, which actually helps to keep this unit nice and simple. The total range of the unit is four octaves, two down to two up. The other selections allow you to step up or down by 2, 3, 4, 5 and 7 tones. It's therefore possible to find most (if not all) of the useful intervals. An unexpected benefit is the "detune" selection, which gives you a kind of static chorus effect, either up or down in pitch from the dry signal. Curiously the middle tuning selection (labelled as "+/-5") gives you a direct duplicate of the dry signal, but delayed slightly. In fact, the wet signal is delayed no matter which setting you are using. I looked at this in a spectrographic display and it seemed to be around 32ms as near as I could tell. Not enough to be off-putting when mixing with the dry signal, but enough to be distracting if using only the wet signal. The quality of the pitch shifted sound is pretty similar to the dry signal, with maybe just a shave of de-emphasis on the treble tones. The sound quality is good enough to allow you to split the signal chain to get useful double tracking in stereo. Overall, this is a lovely wee pedal. It's a bit more pricey than some at a penny off £39, but considering the overall quality I think it's a fair price.

## Questions & Answers

**Q: can you use this with a bass guitar?**
A: Yep. Using it with mine and it tracks fine

**Q: Anyone know what is the correct adaptor for this? Is it available from Amazon?**
A: Any standard 9v, centre negative adaptor will work e.g. Boss, ehx etc. This is the most common pedal adaptor and a huge range exists on Amazon. One I use which is reliable is the boss 9v, 500ma. This has enough current output to be able to daisy chain a few pedals from the adaptor

**Q: Could this double up as reverb or is it strictly delay?**
A: You could set it for a really short rate for that 'slap back' 50's tone or to thicken your normal tone similar to a reverb pedal I guess but it is way more versatile than that. I bought mine 'cos I wanted to capture a tone similar to Slash on 'Welcome to the Jungle' & Dave Gilmour on 'The Wall' primarily & many gear review sites rated it as the best budget Delay pedal out there. For the money it really is unbeatable & I'm really pleased I bought one. You can dial in so many great tones with it.

**Q: Are they nearly as good as boss delay?**
A: quality of sound is as good but no as versatile as a good and lot more expensive boss delay pedal. depends what you want... i only wanted something simple as i don’t use delay very much. good for the money!! good luck!

### ⭐⭐⭐⭐⭐ Donner Harmonic Square Pitch Shifter with Violin
*by R***Y on 23 July 2018*

Donner Digital Octave Guitar Effect Pedal Harmonic Square 7 modes With the kind help of Amazon Returns (cough..), I've been searching for a pitch shifting pedal for a piezo equipped Electro Acoustic Violin. I need an accurate and clean pitch shift for 1 and 2 Octaves Down to give pseudo Cello and Double Bass emulation. I first tried a second hand Boss and then the Behringer copy; Nope, that isn't right. Then came the Ammoon Octa; Nope. Low Octave colouration, good tracking though, guitarists should try it with some filth applied. Then came the Rowin Octpus; Definitely Nope. The dry signal is altered and no attempt at unity gain. Pointless warbly high octaves. The Mk2 Mooer Tender is not the withdrawn Mk1; So what is a budget buyer to do? This little Donner Harmonic Square is a real breath of fresh air after all my searching. The Violin signal is tonally translucent in both, True Bypass and through-circuit Dry Signal. One Octave down is just amazing with a bit of reverb from my old Zoom 504II. It reproduces the bowed sounds brilliantly and some nice harmonics are still available. Two Octave down with pizzicato, I swear, sounds like a double bass! It tracks perfectly and faithfully reproduces the tonality of a bowed/plucked instrument with shifted pitches. I won't be using the High Octaves, because on a violin that just sounds insane..., but if that is what you are after, it can do it. It is not a harmonizer, so the other pitch shift features are of no interest to me. Doesn't come in a fancy box, the value is in the pedal. It has a quality control date mark on the back which was encouraging. A great sounding Octave Pedal for a piezo violin. Can't wait to gig with it!
