The modern guitar - instrument with two soundholes on the upper part of a soundboard. Such a solution gives us many opportunities:
1. The main axis of a soundboard is continuous - the construction is harder and with this - more stable.
2. The angle of a neck creates less tension on a soundboard and makes using high frets easier.
3. Modern guitar has 24 frets - 5 more than in the classical construction!
5. Efficient construction of a modern sounboard exceeds a dynamic range of double-top instruments without having a so-called "plastic sound".
