Donner Tuner Pedal, DT-1 Chromatic Guitar Tuner Pedal with Pitch Indicator LCD Display for Electric Guitar and Bass True Bypass

I moved my music gear to a different room in the house and maybe there is an earthing issue. However, the result was that after moving, I began experiencing a horrible pounding noise from my amp when playing my Telecaster using a distortion pedal. Only the Tele, only with distortion, so clearly "noise" from the single coil pickups. So I bought this Donner noise gate. Put it on the board, adjusted the knob and BINGO - noise gone! Inexpensive, very well packed, and delivered within 24h. Can't fault that.

Good bit of kit, works really well. Helped me dial out the earth hum, until I bought a new power bank which totally fixed my issue. I still use it live though, cuts unwanted noise dead. As with all noise gates, you have to play with it to get the right amount of sustain, or it will drop off to fast.

This is my first Donner pedal and to get usable sounds solely from just this pedal personally for me it took some fine tuning. Can’t quibble too much for the price

Compact, robust, decent quality material. Good sounds for pounds

Use this in A+B mode to split my signal into two outputs on my pedalboard. No ground loop problems or extra noise issues. Great pedal if you want a robust, simple ABY splitter for a low price.

Pretty cool, good for bass sound for busking but there is a slight but somewhat noticeable delay of the wet signal, kinda not an issue if you have the dry signal too, or if you have only the wet signal and aren't playing really precise (like heavy tremolo picking or sweep-picking). Can make up for it by rushing slightly. Would be nice if the pedal came with a 9V clip so you could attach a battery and connect it but otherwise awesome. 5ths (7 semitones) sound good up and down, same with octaves. Haven't played with others yet. The ability to go 2 octaves up or down is actually really cool, leads to some sick sounds. Play with a fuzz and it sounds unbelievable.

My first pedals , Love these , Great sound quality , excellent value for the price , nice build to Them as well good weight also ,

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.

വളരെ ഉപകാരമായി .താങ്ക് യൂ ആമസോൺ. നല്ല ശബ്ദം. കാണുവാനും വളരെ ചെറുത്. നൈസ് താങ്ക് യൂ

Good pedal.

Outstanding distortion pedal....... I am happy with this pedal.....but I am struggling to find a adapter for this pedal......

Très pratique pour avoir mes deux basses sur mon ampli et switch entre les deux, de plus elle n'a pas besoin d'alimentation pour fonctionner, l'alimentation sert uniquement a allumer la LED, je rajouterai que la pédale n'altère pas dutout le son ce qui est fort agréable
