Essential about the Moby Dick is the long neck joint. It creates a great transmission of the vibration from the neck to the body.
Also it is possible to use a very thin neck.
The neck is mounted with ten M5 machine screws. The screws are placed around the fretboard, so it guarantees a perfect playability of the highest frets.
Because there are so many screws, the guitar has a very long sustain, but also a clear, punchy overtone sound.
