Two things top the wish list of
many guitarists looking for a contemporary instrument: playing comfort and
acoustic volume. Looking at custom guitars built over the past decade, you
could conclude that luthiers are giving attention to both areas but that
steel-string makers have focused on ergonomics, while nylon-string
builders have concentrated on increasing the power and dynamic range of
their instruments. Designs such as wedge-shaped bodies and arm-rest bevels
are now common on boutique steel-string guitars, while double tops,
lattice bracing, and other turbo-charging construction details are mostly
seen on high-performance classicals. But some luthiers are starting to
merge these two worlds. One example is Northern California luthier Rick
Micheletti’s patent-pending Rigid Rim guitar (michelettiguitars.com).
Like many classical builders who followed in the footsteps of
Australian luthier Greg Smallman, who uses extremely stiff and rigid sides
and backs as a platform for a high-performance top, Micheletti designed
his latest steel-string around a rigid frame, rather than connecting the
top, back, and sides with traditional kerfing. Laminated from strips of
Indian rosewood, the resulting rim is extremely stiff, similar to a
speaker cabinet, with the top taking the role of the moving membrane. As a
bonus, the thickness of the rim allowed Micheletti to round the edges of
the top and back, which essentially puts a bevel around the entire
body.
The guitar pictured here is the prototype of Micheletti’s design. It
has a Western red cedar top, Oregon myrtle back and sides, and a
five-piece Oregon myrtle and Indian rosewood neck (with a scale length of
25.4 inches). The guitar is X-braced, with two additional lightweight
X-patterns taking the place of traditional tone bars in the lower bout. A
side port provides an acoustic monitor for the player.
It’s immediately evident when playing this prototype guitar that
Micheletti’s application of the rigid rim concept was successful. The
instrument has power, a quick response, and is comfortable to
hold.
