The new Russell slack key guitar is coming along. Here is a close-up shot of the European Spruce soundboard and bracing, showing the fan bracing going through the diagonal transverse brace.

This shot shows the full soundboard fan bracing with two soundholes in the upper bout.  There is a one piece cross-grain spruce reinforcement around both soundholes.  This is a custom soundhole design. By not having a center soundhole and extending the fan braces further up, more of the soundboard will be excited by string vibration.
