CG-12
with "Dual Saddle Bridge"
The
CG-12 is a hybrid instrument with some very unique features, the most
obvious being the "Dual Saddle Bridge". My client's stipulation
on this instrument was to build a combination guitar, comprised of Nylon
and Steel strings, using one neck. Other than that, I was free to design
whatever I thought would work.
The prototype took just over a year to complete.
This instrument is built as a Classical Guitar, body shape, neck width,
etc., with a 26" scale, utilizing a modified Bouchet bracing system,
with specific alterations to counteract the increased tension delivered
to the top and neck by the addition of the Steel strings, as well as
increasing the volume, and balancing the tone.
These Alterations are as follows:
Soundhole diameter increased to 4"
Double acting truss rod in the neck
12 string headstock
Transverse bracing struts at strategic stress points

Bridge is bolted to the top
My main concern in designing this instrument was the separation of the
two distinct tones generated by the Nylon and Steel strings. This brought
about the development of the bridge, which in turn led to the development
of the dual pickup scheme, resulting in a stereo setup, which separates
the Steel and Nylon registers into separate channels, giving a performer
an astounding array of possible sounds, on stage or in the studio.
