Thomann CTG-10 Clip Tuner

Bought this mainly for home use, as I have a pedal tuner for other purposes.

Although it's very light, it does feel nice in the hand - the finish of the plastic is not glossy, rather satin like, almost rubbery, which definitely feels better than just cheapo plastic.
Operation is very straight forward - You hold the button for a second or so for it to turn on, and voila. It is chromatic, and it's both for guitar and for bass. Also, a very nice touch is the fact that there is a backlight , it's blue when You're out of tune, then the entire screen lights up green when You hit the pitch, so it's well suited for low light situations. So, thus far, all good.

The cons that I've stumbled upon are such - on guitars, that aren't exceptionally resonant, it doesn't really pick up the thinner strings all that well - it definitely works, and is usable, but it's not fast as sometimes it won't pick up the vibrations. I've tried it on strats, teles, les pauls, a couple of basses and a classical guitar, and it seems to jump around a fair bit on the strat, less so on the tele and LP, BUT seems to work outstandingly well with basses.
So, if You're buying this for home use, of maybe studio, it is fine - does it's job, sometimes hunts around. All of this is absolutely acceptable, especially considering the price point.
But if You're looking for something fast and responsive for, let's say, live situations, I'd opt for something that's faster/more accurate.

I’ve owned Clip tuners before and their operation was super easy - hit a string, tuner picks up the note, and as you tune the led needle goes sharp or flat until you’re spot on.

This one is suppose to do the same, but unfortunately as you tune it doesn’t keep that note ‘alive’ on screen so you can’t see if you go up or down, and definitely can’t see when you’re in tune. You have to keep stroking that same string again and again to see how far you’ve come along towards that green confirmation that you’re in tune.

It also doesn’t even pick up the right string most times, which is really strange and frustrating.

Maybe mine is defected, who knows, I’ve seen some really good reviews here, so hopefully no one else has that problem. I guess you could expect that for the very cheap price.

The "Thomann CTG-10 Clip Tuner" is one of the cheapest tuners you can buy, because of the low price you could be forgiven for thinking it's not going to much use but it's actually a pretty accurate and useful little tuner.
I usually tune with a BOSS TU-3 pedal tuner when I'm using on my pedal board but thought a little clip on tuner would be useful so that I could tune up without having to plug in and power up my pedal board for a quick practice session, the CTG-10 couldn't be handier for the job.
So far I have used it on my Fender Stratocasters, Fender Telecasters, Fender Mustang, Gibson Les Paul, Gibson SG, Gibson ES335, Epiphone Casino, Danelectro DC59 as well as my Gibson Hummingbird, Martin D28 and Art & Lutherie acoustics and the clip has accommodated all the different headstock shapes and thicknesses with ease.
The tuner is very simple and intuitive to use, a single button turns the unit on and off and the same button toggles between the three modes which are "guitar", "bass" and "chromatic".
To turn the tuner on the button needs to be held down for a couple of seconds so it won't be turned on accidentally in a gig bag or case.
The screen is easy to read and is bright enough to use in the dark but can be a little difficult to see it in daylight or under bright lights.
I have experimented using it along with my BOSS TU-3 and the results are pretty much the same.
It usually works as soon as it's clipped on and only very invasion ally do I need to reposition it to get it to work.
It's small enough that it can be left on the guitar when put away into a hard case and it's cheap enough that you can have one in every case.
All in all a very handy and capable little tuner, really very good value for money.

Incredibly good money for value purchase.

I got this as part of the bundle of my first acoustic guitar and used it constantly ever since (> 6 months). You can use it for chords (useful when you start learning) or just tune your guitar strings. You can also tune bass, which is a nice extra (didn't use it for that, as I don't own a bass yet). The screen turns green when you hit the perfect pitch, which is a nice visual clue.

Be aware that this tuner must be clipped to the guitar in order to process sound. For an acoustic, clip it around the rosette, and for the electric, clip it to the headstock.

I know it's just common sense, but it makes so much of a difference to practice with your guitar always in tune.

Pros: Accurate. It will get you in tune.
The light up feature when you are in tune is nice.

Cons: It struggles to find what note you are on. Sometimes it will get lucky and pick out the right note the first time. All too often it will flounder on what note you're playing. For example, I might sit on the B string and it will tell me I'm sharp for the A string, then flat for the D string before telling me how to tune for B, without me changing anything for that string at all.
It doesn't have access to the full chromatic scale. It will only tell you if you are on one of the standard tuning notes. It tries to tell you if it's Bass or Guitar tuning, but does a laughable job at figuring that out.

All in all, it is functional, but frustrating to use,

I stand by what I wrote in my earlier review with the exception of the final three words: End of, right?; cos it wasn't; the end of the matter, I mean. In fact, it never is when you're a contemporary musician. There is no end (other than...), just perpetual change.

Simply put, I quickly outgrew the need for a simple tuner as described below. I was now in the land of pedal boards and that means: Well, check out my review for the Boss TU-3 and you'll see what I mean... end of, right? - unlikely; very unlikely.

*** Original Review ***
A good friend of mine recently paid a small fortune for a very similar piece of kit. Don't get me wrong: It works well; it is fit for purpose; it assists with tuning a guitar; he is happy.

Now, I have seldom found myself in need of a tuner before, for one simple reason: Just like many other guitarists and bassists, I can tune a guitar or bass perfectly well by ear. I do concede that, on occasions, I would ask my keyboard player for a "middle C", just to make sure but, other than that; no, there was no justification for such an accessory; especially at the prices I was being quoted.

However, I now find myself playing bass in a band with a compliment of three relentlessly noisy guitarists. Therefore, rather than having to utter a continuous stream of expletive ridden edicts, telling them to shut up, so I can check my tuning, I decided to buy this little tuner.

And, like my friend, I am happy. Why?; because, despite costing a fraction of the price of certain expensive imitations, it also works well; it is also fit for purpose; it also assists with tuning a guitar, bass, etc., or any other of a huge range of musical instruments.

Simply put, there's no real excuse for not being able to tune your instrument, although I meet many who can't, allegedly. But, if you find yourself in circumstances similar to my own, beware of expensive imitations. It's a tuner! Pay a small ransom, should you so desire, but surely a fit for purpose, incredibly well priced option, such as the CTG-10 Clip Tuner is the best way to part with your hard earned cash. Of course, it's your call but, take my advice: if needs be, get yourself one of these little beauties. Easy to use and great value. End of, right?

I was looking for a cheap tuner for my guitar, and I stumbled upon this one. I already had a tuner pedal, but I wanted one that could be more accessible. Also, I could use this one on my acoustics.

For the price, I really cannot have any complaints about this tuner. It has 3 settings, Guitar, Bass and Chromatic, so it covers pretty much all the areas I was looking for. It is quite accurate, even compared to my Korg Pitchblack pedal. The display is bright enough so you can easily see it in the dark, really helpful for live performances. I've been using it for about two years and the battery still goes strong.

Compared to previous tuners of the same price range I've used, this one, while not amazing, is probably the most responsive one. It does have some issues though, there are times where it takes a while to register a note you play, so you have to wait a bit for it to "reset". Also, while the build quality voerall is fine, it does have a cheap plastic look.

Overall, for its price, I cannot reccomend this tuner enough. I've used it for two years and it hasn't let me down yet.
