Acoustic guitars with tuner included

Tuner

— a guitar tuning device, roughly speaking, is an “electronic ear” that listens to the frequency of the sound of the strings and determines whether it corresponds to the reference values. All tuners work according to this principle, and anyway, the presence of such a device in the kit can significantly simplify guitar tuning. However, the specific capabilities in each may be different. For example, the simplest models are able to work only with the traditional system and determine deviations from the standard only at the “higher” or “lower” level, without details. More functional devices can display a sounding note or even a specific sound frequency, be able to transpose (increase or decrease reference frequencies), support non-traditional tunings, etc. The package includes mostly inexpensive tuners, but there may be exceptions, so the details should be clarified separately.

Note that in this case, the tuner is meant as a separate device. Electric-acoustic guitars (see "Type") have built-in tuners, see "Advanced" for more on this.
