This special concert guitar is build according to the wishes of the musician who wanted a very ergonomic instrument easily to play. Therefore the frets are arranged like a fan meaning the scale length for the bass strings is longer than for the trebles. This helps changing the fretboard positions with less work for the left hand. Additional the right upperbout of the guitar next to the fretboard is lower like an invisible bevel cutaway to help playing in the high position.
The neck of this special guitar is veneered with ebony. This provides a smooth touch of the neck without sticking while changing the positions.
