Traub - Joseph - special edition "lunar"

This Traub "Joseph", special edition "lunar" is a jazz/acoustic guitar hybrid. The top is arched like that of a jazz guitar. The two backs of my unique double-back system are built like those of an acoustic guitar. The outer back as well as the frame are made of 3000 years old bog oak and the inner back - the sound producing one - is of shell maple. I built it with a scale length of 650 millimeters, whereby the height of the strings may be adjusted manually by means of a beautifully designed height adjuster.
