Comparison Yamaha FGX800C vs Yamaha FX370C

The presence of a built-in tuner in the guitar tone block (see above).

The tuner is used when tuning the guitar: it “listens” to each string and tells the musician how much the pitch of its sound corresponds to the reference (higher, lower, normal). This equipment greatly simplifies the setup. Tuners can also be produced as external devices, however, the presence of such electronics directly in the tone block is much more convenient: at least, it is always at hand and is not lost. For more details about the features of such devices, see "Tuner" below.

Scale length of the guitar. The scale in this case is the working part of the string, in other words, the distance from the saddle (on the headstock) to the saddle (on the bridge). In most acoustic and similar guitars, the scale is set during production and is unchanged. Without going into technical details, we can say that the value of this parameter is generally a reference: it allows you to some extent estimate the overall dimensions of the instrument, as well as the size of the frets (the longer the scale, the larger the size of the frets, regardless of their number). However, there is also a practical application: with an adjustable anchor (see above), the scale length data can be useful in the tuning process.
