Voicing and Construction

I planned to build a classical guitar with open harmonic bracing based on plans from Guild of American Luthiers. This ukulele was a practice run of the bracing pattern. The cross brace openings have a 0.5mm strip of Spruce against the top. The width of the five fan braces varies from 3.5 to 5mm.

Top thickness 1.6mm to 1.5mm perimeter. Back thickness 1.9 mm.


Top monopole 365 Hz

Top cross dipole 480 Hz

Back 403 Hz

Air 196 Hz
