How to learn to distinguish a good guitar from a bad one?
Main criteria for choosing an instrument.
Part 1 "Attack"
----------------------------------------------------------------------------------------------------------

The initial idea was to present a new guitar, recording several works on it. The luthier asked me to play five Catalan songs by Miguel Llobet, taking into account the peculiarities of the instrument's design.
But the July presentation of the new guitar by Timophey Tkach didn’t confine itself to just playing.
Often musicians who already play at a fairly high level can’t understand what kind of instrument they are holding in the hands and are guided solely by intuition and purely personal feelings. The judgment of a guitar usually boils down to four or five trite phrases: "is comfortably to play", "strings are not high", "what a deep bass", "sounds like a grand piano" and "a terrific sustain". The last two characteristics come from aesthetes :) I'm often asked questions about the choice of an instrument, but I thought it would be right to address them to the luthier whose opinion has been authoritative for me since we met. All the more so because you, the subscribers to the channel Classics of Sound DN, were okay with it. Timophey's answers have come out very detailed, so I decided to divide them into four parts.
The first part is "Attack".
