The neck/fretboard is one piece through-and-through laminate of bird's eye maple, solid carbon, padouk, carbon, bird's eye maple. The truss rod was inserted before the laminates were joined, although useless, that carbon has no flex.
It sounds like a stingray on steroids and beef. Not quite as much honk as my SR5 (in a good way) with more fundamental and higher overtones. A richer, lively sound, easy to hear in a dense mix and sustain for hours. Fairly high output, drives pedals and amp well.
