Donner Tremolo Guitar Pedal, Golden Tremolo Analog Effect Mini Pedal for Electric Guitar and Bass,True Bypass

The sound was okay for the price but I was looking for something with a bit more overdrive. It's good value for money though.

It did what it's meant to do at a good price! What more is there to say???

Hi. This is not really a review but I bought this pedal today for my bass. When it’s plugged into power and connected to the bass and the amp in the correct in and output but the pedal is off, sound passes through it into the amp no problem but as soon as i turn the pedal off, there is no sound. What could be the problem? if anyone could reply to this with a solution, that would be a huge help!

Excellent pedal. Small, good looking, great sound, well built.

ideal end of chain analogue delay - This isnt a feature packed sculptor of exotic sounds but it puts the finishing touches to your tone. Works well with other pedals eg: compressor, eq pedal and overdrive - If you are looking to find your own sound on guitar this might be the pedal for you

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.

Nicely built, reasonably intuitive controls (once you realise that 'detune' is pretty much a chorus effect), doesnt take up too much space on the board.Good control over the level of wet and dry signal.3x7-21 ways to use the wet signal but for most I think the most useful settings are - one octave down - this (and the -2 octave setting) gives an effect similar to a bass guitar replicating the lead riff/melody. - two octaves down - up a fifth (7 semitones) - chorus / detune - up an octavethe latter two - and even more so for the up-two-octaves setting - can sound a bit harsh / synthesizery if you are a long way up the neck, so I'm wondering whether the wet signal is largely reduced to the root note frequency / sine wave.I haven't yet found a use for the other settings, but those more experienced/ creative than me might put them to good use.No a dirt cheap pedal, and not the first pedal that a beginner should buy, but I'd recommend it at the £40 ish I paid for it.

This does sound pretty good, kind of reminiscent of a Boss DS1 out of the box. I run it stacked with an overdrive pedal and it sounds awesome, though a noise gate is required to take out the excess buzz, only to be expected. It's got a nice range of tone giving some pretty dark and almost fuzz like tones right through to brighter, classic rock type tones. I'll update after I've had more time to play with this, but so far I'm pretty happy with it.Now that I've had this for a couple of months and I'm liking it a lot. Having played around with its settings and stacking with a Klon clone overdrive, I'm getting some very Rat-like tones with this thing and it is definitely showing that you don't have to spend a fortune for great tones. I'm very impressed by the value for money, build quality and usability. At the price this thing sells at, it's a definitely a worthy consideration for guitarists on a budget and even those with more cash that aren't too worried about what brand names are on their boards.
