KorgCA-2 Chromatic Digital Tuner for Stringed, Woodwind and Brass Instruments - White

I use this to tune synthesizers and it works perfectly both with the mic and the input.Could be improved if it had a backlight, it can be hard to see sometimes.

At last, a tuner that is truly universal. It recognises every note including flats and sharps. Most tuners cater for guitar or similar and give the srting number too and don't recognise those notes (like C and F plus all sharps and flats) which makes them as much use as a chocolate fire guard when tuning a 32 stringed autoharp.Excellent, thank you.

You need a good tuner for your guitar or ukulele, easy to use, comes calibrated at 440 MH which is correct for guitars, good value, Regards, Ray

This is a good tuner for the price - seems accurate when tested against my other devices with high end tuners built in. Great size. My only criticism is that the yellowed plastic on the back makes it look dirty and almost nicotine stained.

As a novice alto sax player, at first I had problems using the tuner and the vague quick-start guide that came with the device didn't help at all.So I emailed the manufacturer and was sent two links to their official guides almost by return. One was the guide referred to above, the other - which was far more helpful - the full CA2 manual (note to Korg: why not replace the first with the second?). In addition, there was a phone number offering further help if needed.This was no empty gesture. As I was still having problems I phoned the company and was put in touch with Jahan Tabrize, the sender of the first email. Not only did he take the time and trouble to explain how to use the tuner, but he also sent me links to Youtube videos on how to tune an alto.In short, Korg's customer service was second to none. I can't recommend the company and its product highly enough.

The most inaccurate, unresponsive tuner (for classical guitar and lute) that I've ever owned. I'm amazed that a well-known manufacturer could release such a product.

Great little tuner. Takes 2 AA batteries. Easy to use. Display will change with the note played, I have it constantly connected to the oscillator tuners on a modular synth and it works perfectly

I have recently started playing the sax and without spending too much money this product meets my needs at a fair price. I recommend it to anyone like me who approaches the saxophone for the first time.
