How to distinguish a real IBANEZ550 from a fake?

Now the technology of Chinese counterfeiting is getting higher and higher day by day, and even the RMB we use every day can't be distinguished, let alone a piano.

The feel of parallel goods is almost the same as that of licensed goods, I know a friend who runs a piano shop, which is imitated by the manufacturer, if he doesn't say that I really can't recognize it!

If the landlord wants to buy it, I recommend going to a piano store authorized by a special manufacturer, so it is more assured!

There is an anti-counterfeiting number on the back of the headstock, and you can check whether it is true or false by entering this number on the official website of IBANEZ.

You can first look at the after-sales credentials and product information to check.

It can also be preliminarily identified by verifying the quality of the instrument, such as the timbre and the quality of the strings.

Although there are a number of guitar manufacturers in Japan, there are not many that are well-known and established overseas. In a sense, IBANEZ is a premium brand in this category. Even the tiny parts are made with great detail, and to this day they are still the darlings of guitarists in the rock world.

The practicality of the Ibanez guitar and its suitability for all genres** is a big reason for its popularity.

You have to know what the IBANEZ factory code represents refers to, the initials of the table which place of origin, the specific model is only in a specific factory, the number represents the date of manufacture, like 7V, the noble series are F prefix on behalf of the Japanese factory, many fake 7V can be seen at a glance from the number. This era of fakes flying all over the sky, the two-in-one code may not be true. The best way to do this is to understand the characteristics of the various Ibanez bridges, and this is the only one that can't be faked.

IBANEZ is currently a low-end entry series of GRG series but there are relatively few imitation pianos, the most imitated are the old RG270 and RG470, these two have been classified by Hoshino Musical Instruments into the GRG series, that is, the domestic series, at the same time the most common is 7V imitation piano, it is simply overwhelming, 7V is easy to judge, look at the workmanship of the bridge and the workmanship of the piano yard, in addition, look at the **, 7V is almost out of stock now, if you can find it casually, then it must be an imitation piano.

You get what you pay for, you can't do it without a few Q yuan, and you can go to a regular piano shop. It is difficult to tell whether this is true or false, even if it is a professional pianist, and there are many imitations in all walks of life.

This one is more difficult.

For Korean and Nissan, you can go to the official website to check the authenticity of the code on the back of the headstock.

Domestic and Indonesian products cannot be found.

Now many domestic imitation IBAs are difficult to distinguish between real and fake.

Ibanez is now a lot of imitations in China In fact, I don't dare to say that I understand the 270 that my friend bought was blinded Buying a piano is not better than buying something else Buying a satisfactory piano can make you happy The feeling of playing is good If you don't buy well, it's counterproductive What you said upstairs is also very good Although it is a copy I suggest that you find someone who has been playing the piano for a long time to accompany you Experience will be much better in all aspects Listen to the sound quality of the piano The feeling of being able to penetrate the heart can not be fake I hope you buy the piano you like.

Differential diagnosis:

Both true and pseudomyopia manifest as decreased distance vision and good near vision.

Pseudomyopia is functional, more common in adolescents, and vision can be reduced within a few weeks or 1 or 2 months, and can be restored to some extent with appropriate rest. True nearsightedness is an organic change.

**Principle. Pseudomyopia is only an abnormality in the function of ocular accommodation, this change is reversible, correct bad eye habits in time, and then cooperate with the best method of relieving eye muscle fatigue.

On the surface, pseudomyopia and true myopia have the same manifestations, that is, they can see far and clearly. But looking at the essence through the phenomenon, the difference between the two is obvious. The so-called pseudomyopia is caused by the frequent incorrect use of the eye, the ciliary muscle continues to contract and spasm, and the lens is in a state of thickening.

In this way, the parallel light from the outside enters the eye, and after the atrial refraction of the thickened lens, the focus falls in front of the retina, and it is naturally not clear to see things in the distance. During this period, there are no organic changes in the eyeball, and if you can take proper rest and **, pay attention to eye hygiene, and use the eyes reasonably, there is hope to restore normal vision. However, if it is not corrected in time in the stage of pseudomyopia, it will develop into true myopia over time.

**There are many methods of pseudomyopia, mainly relaxation and regulation, such as: the use of cycloplegic agents to dilate pupils, acupuncture, physiotherapy, improve the learning environment, pay attention to eye hygiene, and do eye exercises seriously.

If pseudomyopia is suspected, you can go to the hospital for eye examination, the doctor will use mydriatic drops to dilate the pupils, and after the cycloplegia is examined and refracted, if there is no change in refraction, and the vision improves significantly or returns to normal after mydriasis, it means that it is only pseudomyopia. If there is a corresponding change in myopia refraction after mydriatic palsy, and the visual acuity does not improve after mydriasis, the corresponding myopic diopter vision can be improved, which is true myopia.

Both true and pseudomyopia are characterized by decreased distance vision, which is better and more difficult to distinguish.

True myopia, also known as axial myopia, true myopia is an organic change that cannot be recovered naturally.

In pseudomyopia, there is also a partial adjustment effect when looking at distant objects. On the surface, pseudomyopia is also blurred vision at afar, and clear vision at near and near, but there is no corresponding refractive change during dilated refraction. This situation mostly occurs in adolescents, and after taking the necessary methods, vision can be improved and restored.

Eye health has begun to move towards a younger age, and many children have been nearsighted since elementary school. It brings a very serious safety hazard to the child. Many parents are worried about ** myopia, for children under the age of 18, because of the strong ocular accommodation at this time, it can also be improved by drugs.

It is recommended to use Leyan nutrients to treat I, take it with warm water twice a day, adhere to the use of pseudomyopia can recover quickly, and true myopia can reduce the degree and improve vision.

1. Do not distinguish pseudomyopia by degree: Many parents believe that the first appearance of low-grade myopia (myopia below 300 degrees) must be pseudomyopia. In fact, true or false myopia is not judged by the degree.

Once the child is found to have blurred vision, he must be taken to the hospital for eye examination, and the doctor must pass the dilated eye examination to determine whether it is true myopia or pseudomyopia.

2. Pseudomyopia: refers to the disappearance of myopia after dilating the pupil with mydriatic agent, presenting as emmetropia or mild hyperopia, and myopia disappearing, which is called in medicine"Pseudomyopia"(Modulating spastic myopia), which is more common in children and adolescents who are younger, have a shorter onset time, and have a lower refraction.

3. True myopia: refers to the fact that after the use of mydriatic agents to dilate the pupils, the refractive degree of myopia is not reduced, or the degree of reduction is less than the degree.

4. True myopia with pseudo components: It refers to the fact that after the use of mydriatic agents to dilate the pupils, the refraction of myopia is significantly reduced (the degree of reduction), but it has not yet recovered to emmetropia.

5. Pseudomyopia and true myopia have the characteristics of visual fatigue, poor distance vision and good near vision from the symptomatic point of view. However, pseudomyopia is a functional change, and there is no problem of the anterior and posterior diameter of the eyeball becoming longer, and most of them can be turned into farsightedness or emmetropia after being spotted with cycloplegic drugs.

Prevention of myopia requires a good visual environment, that is, the illumination of reading and learning should be above 300 lux; Maintain a good sitting posture; Supplement the eyes with nutrients such as fruits, vegetables, and lutein; Conduct regular eye health screenings to ensure that problems are detected in a timely manner. Pay attention to "66 Love Eye Protection" and continue to pay attention to eye health with us.

Pseudomyopia is a low-degree myopia that appears at the beginning, generally within 100 degrees. When cycloplegic agents are used, such as dropping atropine ophthalmic gel for a week, the prescription disappears and distance vision also improves, indicating that the original myopia belongs to pseudomyopia, also called accommodative myopia, which is caused by excessive use of the eye. If the prescription does not change after the cycloplegic is dropped, and the prescription is still the same, this situation is true myopia.

It is important to note that pseudomyopia lasts for a short period of time and will soon become true myopia.

Usually pseudomyopia is caused by eye fatigue caused by unreasonable eye use, lack of outdoor exercise, lack of sleep, etc., while true myopia may be caused by the elongation of the eye axis caused by long-term eye fatigue. It is recommended that you can choose a regular public hospital ophthalmology examination vision, optometry and audition, if there is indeed a problem, first dilate the pupils, in general, pseudomyopia can be removed, after the pupil is restored, if the naked eye vision is lower than normal, and there is myopia, it is considered to be true myopia, and it should be corrected with glasses.

If you want to distinguish between real and false myopia, you need to go to a professional eye hospital for dilated refraction, which is performed when the ciliary muscle of the eye is completely paralyzed by applying drugs, so that it loses its regulating effect.

The tones I know are different. The instruction manual is different from what the teacher told me before.

My own is a hand, very good, it feels very good, especially the push string, it is absolutely amazing, and it is much better than my own Mofen.
