Korg - CA-2

An unpretentious little tuner which I find excellent for quick tuning of bagpipe drones. There are more complicated tuners out there, but this one is a stable and accurate performer.

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.

This I liked straight away ease of use but the tone is a bit of mystery

Fine for price

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.

I've had this CA-2 tuner for about 6 months, and it's suddenly started acting up. It works with a jack connected, but using the internal mic it just goes haywire. Even in complete silence the needle just goes crazy, and it doesn't respond to any note you play. I put a new set of batteries in but it didn't make any difference.My guess is the internal mic has a bad connection on the PCB, creating a buzzing signal that the tuner interprets as random notes.I expected more from Korg, especially as I bought this to replace a CA-1 that I'd used for well over ten years without issue. Disappointed, and will be looking elsewhere for a replacement.

Thoroughly enjoy using this. It’s very accurate. Simple to use. Makes my hideous cello practice sound at least in tune. Haha

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.
