Question bête : comment tester une acoustique

Je voulais donc juste savoir s'il y avait une astuce particulière ...

When you play a standard acoustic guitar, you never hear the true sound that the guitar is producing. Why? Because what you hear is reflected sound. Have you asked someone to play a guitar for you, so you can hear it? Maybe you have played a guitar in a corner, or close to a wall, so you can hear it more clearly. Do you find yourself leaning over the side of the guitar, or angling the guitar upward, so your ear is more in line with the sound hole? If so, read on ...

Now, with the benefit of a McKnight Sound Port, you can hear the true sound your guitar is producing. The sound port directs a portion of the guitars true sound to the player. The results are truly amazing! It is like having your very own personal sound monitor built into your McKnight Guitar.

Blindfold tests prove that there is absolutely no loss of energy with a sound port. In fact, the results are quite the opposite. There is a discernable gain in sound hole projection, as well as a 360 degree sound gain around the player.

un ami l'a jouée et j'ai découvert une autre guitare : manque de projection, son sourd, étouffé ..
