Testing Acoustic guitar
First, in the comfort of the Acoustic guitar. The instrument must be comfortable, pleasant to hold, that does not resist when we try to adapt to its dimensions. A Acoustic guitar can gather all the virtues of the world, but if its mast, body, buttons, etc. they are uncomfortable, the interpreter will never be comfortable. Sometimes it is not a question of weight or dimensions, but of “feeling”. What does it matter? comfort is essential.
The adjustment. Is the Acoustic guitar tight? This section involves some complexity and, if you are a novice, the best thing will be to have someone accompany you to prove this. Although every guitar can (and should) be adjusted periodically, the ideal is that it already is.
a) The mast divides the scales in semitones, corresponding with each of the frets. If the guitar has 24 frets, the note produced by a string “on air” (without pressing any fret), must be the same as that produced by the frets 12 and 24, that is, its “octaves”. A guitar has to be well octave, which will indicate that the curvature of the neck, size of the frets, etc. they have been well calculated (all this obeys to principles and physical laws that would extend us in excess). We can check it by playing natural harmonics, based on the ear or with the help of an electronic tuner, but the notes have to be exactly the same, regardless of the fret chosen to interpret them. Sometimes the old strings have a tendency to vibrate defectively giving the feeling that the guitar is “uncolored” or “unoccupied”, so it is important,
b) The height of the frets.Although this point is very much related to comfort, the height of the frets or “action” is crucial when interpreting certain phrases. If we want to play fast, or use tapping and play technically complex solos, the fact that the action is as low as possible can greatly help. Always try to avoid that the strings trasteen (that is, they touch the frets when vibrating and its sound is unclear or unpleasant), so the low strings, although they help, will always have more tendency to fidget and give less clear sound. On the other hand, the sound will be sharper with the high action, since there will be more mast-string space to allow vibration. However, bends, trappings and fast phrases will be more complex.
c) Mast and “hardness” of the strings. Another aspect that intervenes directly in the ease of execution is the thickness of the mast: a thick mast will make it difficult for our fingers to “fly” over the fingerboard, but it will make the bends easier, since we have mating surfaces. Another advantage of the neck with body is that it improves the stability and resistance of the guitar. A thin neck is more comfortable for quick sunning, but it is also more flimsy. In spite of this, depending on dimensions, tension of the strings, height of the same, etc. there are guitars that are comfortable, “soft” to play with, and others that are harder and less comfortable at the beginning,
The sounds from the guitars are normally tested with quality amplifiers, which may throw us a little bit off from the true sound of what we are testing.
If we have to summarize the test process in three aspects, I would describe comfort, sound and feeling. And of course, feel comfortable also with the price. In the market there are hundreds of models, imitations, brands and possibilities that can fit almost any pocket. But, not all the guitars give the same, comfort, sound and feel as like acoustic electric guitar. So once that initial selection (required) has been overcome the most important thing is that the instrument is comfortable with the sounds as we expect. NEVER force the machine, and buy Acoustic guitars with which it is difficult to play what we usually play.
