Donner Reverb Guitar Pedal, Verb Square Digital Reverb 7 Modes Room, Hall, Church, Spring, Plate, Studio, Mod, True Bypass

Very pleased with this. I’m playing bass through it and it sounds great. As good as my old boss compressor sustainer I’d say but less than half the price. I have a donner tuning pedal also which is great too. No hiss when treble is high and compression on full which is nice and the bright boost is a welcome addition. It’s very compact but the casing is sturdy metal unlike some pedals at this price point.

Great value and works as expected

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.

I had finally got round to building my pedal board.I had been collecting pedals over time and when I'd come to play, I was getting annoyed with the time it was taking to set them all up. Then I'd forget cables, power supplies, etc., and end up annoying myself.My mates had been telling me over and over to build a pedalboard.So, I got a board, and went about assembling the six pedals I though I had, to discover I had nearly double the amount. Yikes!Anyway, once built, isolated power supplies used and quality patch cables utilised, I was still getting noise.I have a couple of different overdrive and distortion pedals along with a boost pedal.If I want to go from clean to overdrive, I'd naturally incorporate some noise.So I asked my mates and they said to stick a noise gate at the end of the chain.Did some research, and this little box came up at about 4th on most lists and the price was right brand new on Amazon. I'd seen good reviews for other Donner pedals although never owned one so: Click, Click and it was ordered.It arrived in a couple of days. Boxed. Nothing really fancy about what you get: pedal and short instruction sheet, but what do you actually need?Stuck it on the end of the chain after the boost and it just works. No noise.The only pedal it can't tame on my board is a Blackstar HT-Distx, but that one's such a nasty beast of a pedal, if you're using it, you've just got to expect you are going to make noise.So I'm well happy with it. It's tiny as well so takes up little space. There's rubber on the base that has to be removed to get velcro to stick to the pedal board, but that's nothing new. It's solidly built and easy to operate.All in all, a cracking little pedal. Did exactly what I hoped it would do. Nothing more. Nothing less.

I bought this recently along with the Yellow Fall. I've been using this as a mid boost and it's decent for that. As a distortion effect, I haven't really got used to it. It is very mid/bass heavy. I'd recommend it if you want a good cheap boost.

The Donner yellow fall delay. I bought this delay almost 9 years ago when they first came on the market and it has never failed, It is a digital creation of an analog delay and sounds very convincing with warm and degenerative repeats. I have quality delays from MXR carbon copy to memory man and tc electronic and this fits in very well so much so that I use the yellow fall probably as much if not even more. As you can see I recommend it and would replace it straight away if ever it failed. Just remember always use an isolated power supply.
