Those who play instruments know the importance of their tuning prior to any practice or presentation, since the sound quality of each performance will depend on it. In this sense, acquiring a tuner, more than an expense, is a true investment that every musician should make. Therefore, we present you a guide to buying the best tuner, in which you will find the main quality indicators to verify.



If the product we are planning to purchase incorporates a screen, no matter how small it may be, you will have to verify certain aspects regarding its operation and manufacture. In this way, you will get a better user experience when manipulating it and reading the data expressed in it. In this sense, instrument tuners could not be the exception, so you should stay tuned and inquire about this important component. Thus, you will not have future problems when carrying out the calibration.

If you review the tuner comparison lists, you will find that most designs incorporate LCD-type screens with a good level of resolution, which allow you to give a quick read with just a glance. Also, such equipment is usually provided by a backlighting system, which is quite convenient at times when ambient light or from stage reflectors is limited. It is also important that you check that the screen has a preferential rotation of 360 °, so that you can vary its angle and adjust it as best as possible for your comfort.



All instrument tuners require a certain level of energy to start up, so they usually incorporate lithium-ion or alkaline batteries, as provided by the manufacturer. In this sense, prior to purchase, the important thing is to check the autonomy offered by the energy accumulator. Remember that it will be useless to buy an inexpensive tuner, but whose batteries run out quickly, since you will have to constantly invest in spare parts.

Although the lithium batteries integrated into the tuners usually offer a longer useful life than that of the AA or AAA alkaline batteries, it is also true that they tend to be more expensive and may even require the help of an expert to be inserted. However, manufacturers have dedicated themselves to providing their devices with special systems, which, after five minutes of inactivity, automatically turn off the tuner. In this way, the energy saving is remarkable.



The tuner models are usually varied and among them stand out those that incorporate a convenient clamp, arranged to fix the screen safely on the instrument’s headstock.

It is a very popular type of tuner among users, which, if you do not know how to select, could cause inconvenience or offer a short useful life. Therefore, when thinking about acquiring it, you should review some details such as the manufacturing material, which should be a polymer with a resistant and light body. Also, do not forget to check the opening level of the clamp, trying, as far as possible, that it is not less than two or three centimeters. Remember that the correct placement on the headstock will depend on this specification, whose thickness will inevitably vary depending on the model and type of instrument.



In any product, the accessories incorporated by the manufacturer into the purchase package are a very flattering aspect, which generally help us to improve the experience of using the equipment and even to take care of it. In this sense, the tuners could not be the exception. Perhaps this can influence a bit how much the device costs, but ultimately we will end up saving money, by not purchasing the built-in items separately.

The main complement attached to this type of device is the batteries, which is quite convenient so that we can start using the tuner from day one, without any delay. Similarly, the models are provided with a microfiber cloth to properly clean the screen, eliminating dust and fingerprints left when handling it. In addition, other brands offer with the purchase a small case, so you can store the tuner and protect it from deterioration.
