The Korg CA-30 is so simple to use that the instructions are not really needed.

The size is small enough to fit in a shirt pocket.

Now that it is available for less than $20.00, no instrument case, gig bag or accessory kit should be without a tuner.

Gospel, C&W, Oldies, etc.

It catches most of the notes exect on the high-E it has a lil trouble.

Everything you need, from 410 to 480 hz ( i think that's it ) and all the notes, not only the EADGBE type tuners.

it will break if i throw it but its made small enough and easy to transport. it will last

a bit high for tuners. but compared to other tuners, it's good

never had to deal with em

i have it

I teach middle school orchestra and purchased 35 of these tuners for my students' use in class. They have all worked perfectly (except for one, which has an inoperable green light, but the tuner works perfectly, besides that). I'm going to buy another 35 for my high school orchestra. Would recommend these to all musicians.

out of 35, one has a minor defect-the green light does not come on.

Good little tuner the mic is really good. I wish it had an output jack on it though

Very solid plastic hasn't failed me yet

This tuner is well worth the money which is not much only $19.00

I use it to tune an acoustic guitar, jazz guitar, strum stick, and piano. It is precise and easy to use. Never wrong.

It is compact and can be taken anywhere. Sturdy plastic. It would be nice if I didnt have to worry about batteries. Excellent mic for picking up the sounds in order to tune.

No complaints. Have dropped it on the floor with no problems. Excellent for trips or travel. Always reliable.

Definately worth the price. Wish I would have found it online before buying it in a music store.

Dont know about support. Product is so reliable never had to use support.

It is practical and a technical marvel.

I bought one of these from my local music shop. Within one week of treating it as gently as a baby, it started turning off randomly. I figured it my be a loose connection, so I gave it some taps (the sort you do when you're bord in class and feel like drumming on the table, but not so loud as to disturb anyone) and the thing would turn off. Just a good 3 or 4 light taps is all it took. I brought it back to the store and got it replaced. My new one started doing the same thing in a matter of 2 days.

Haven't talked to them yet as it is Sunday. I never complain to companies, but this is outragous. We'll see how they do.

sometimes a little off but all around its great

does what it says

just dont drop it and u will be fine

yes

easy to find at a good price

the best

I use it as an input device.

It can be used to tune any instrument.

The quality is adequate for the price.

This is a great product for the price.
