Plug in your electric instrument, a pickup for your acoustic, wind or brass instruments into the 1/4 in (6.3mm) input jack or use the built-in microphone. WIth all these important features, the MT-40W is tough to beat! Review: Loaded with features, very intuitive and easy to use. Doesn't get better than this for this price. - Excellent metronome and tuner which would be a good buy even if it was twice the price. Easily compares to the far more expensive products by Korg etc. The size is very pocket-friendly and the indicators on the display as well as the button controls are intuitive and provide good feedback. Switching between the tuner/tone-generator and metronome is straightforward too. I found that the tuner was very accurate when directly plugging in my guitar and was serviceable when using the built-in mic although I found that I had to get the device pretty close to the amp/speaker for it to register the frequencies through the mic. The tuner offers fairly granular frequency indication which is good for optimising intonation on guitars with floating bridges. As for the metronome feature, it's actually quite feature rich and offers more than what I'd expect at the price. You get multiple beat and note combinations which are easy to cycle through and select and the oscillating visual indicator along with the 2-colour LEDs that indicate a beat with the green LED and ticks with the two red LEDs re about the maximum visual input that any metronome can give you. The speaker is not the loudest-- probably is just a small piezo tweeter and quite similar to what you'd get on any pocket metronome so don't expect to be able to hear the beeps over a 10w practice amp unless you plug the metronome in with an aux cable. I have used it on occasions with a smaller 5w amp when practicing late at night and with the volume on the amp set at aroudn 30%, I was able to hear the metronome just fine. Battery life is pretty good but I'd highly recommend using alkaline cells or standard zinc cells by a decent brand. The eveready cells died with 3 days and then I switched to duracell that have been going strong since 3 weeks now. Overall, a great device with loads of features and decent build quality and reliability. Review: Well it serves its purpose. - Pros : Guitar tuner ok.... Batterry life doing just fine after 6-7 months , have even option for different strum/lead timings and the ability to tune guitar in different majot/flat keys. Cons: should have had a better louder speaker, the manual should be a little richer or better detailed to help use options. But it serves its purpose and any ways I am not a professional musician... It is good! ## Features - Tuner Tuning range：A0(27.5Hz)~C8(4186Hz) Tuning mode：Chromatic，Wind instruments Tuning key：C, F, B♭, E♭ Tuning precision：±1 Cent A4 range：430~450Hz Detection method：Mic, Line-in Display mode：LCD display, LED display Tuning method：Auto - one Generator Reference tone range：2A~6A Reference tone precision：±0.5 cent - Metronome Tempo range：30~250 bpm Beat：0~9 Rhythm： Tempo precision：±0.3% Metronome sound：Electronic sound Power supply：3V(2xAAA)batteries Dimensions：105(W)x18(D)x65(H)mm Weight：75g - Power supply：3V(2xAAA)batteries - Dimensions：105(W)x18(D)x65(H)mm ## Technical Specifications | Specification | Value | |---------------|-------| | Product Dimensions | 10.5 x 1.8 x 6.5 cm; 75 g | | Item model number | MT-40W | | Item Weight | 75 g | | Manufacturer | Cherub | | Country of Origin | China | ## Images ![MT-40W METRONOME & TUNER - Image 1](https://m.media-amazon.com/images/I/71HT4AkqABL.jpg) ![MT-40W METRONOME & TUNER - Image 2](https://m.media-amazon.com/images/I/61J9xJHhf3L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Loaded with features, very intuitive and easy to use.
