The basic characteristic of double top Koumridis guitars is the volume and the sustain combined with melodic creamy trebles and deep basses. Double tops are made with nomex core and cedar. The projection and the almost endless limits of volume of this instrument makes it to resemble more to a piano than a guitar. The play-ability of these instruments is at the highest level and even normal tension strings produce deep and full sound. maybe they are the ideal instruments for someone who seeks a concert instrument with high volume and pure classical guitar sound.
