Our Acoustic Guitars
Our Der Hauser (pictured left) has it's
origins in the most famous classical
guitar ever! Andres Segovia's 1937
Herman Hauser. In my meddling and
modernization, I Have eased the curve
at waist little bit and added 12.7mm
(1/2") to lower bout rounding it more
than the very flat bottom. I have also
on later instruments than this one
pictured added 9.53mm (3/8") to the
thickness of the guitar.
It has our Sculptured Almost
Brace-less Biplaner top utilizing either
our classical 2V2X bracing system or
our FB5M bracing system.
The back is also Sculptured Biplaner with the inner skin of the back is Hemlock there no
braces on the back . The sides are .070" thick and comprised of 3 lamination with a core
of Hemlock in 90 degree orientation. The fingerboard is of Gabon Ebony with a scale of
650 mm with body neck junction at the 12th fret. It has total of 21 frets. The neck is easily
removable and adjustable in 3 direction and has a double action truss rod.

The Southern Star
Southern Star pictured
has our Sculptured
Biplaner top with our MMX
bracing system and a
traditionally placed sound
It can also be ordered with
our Sculptured Biplaner
2V2X bracing system with
our Epaulet Sound Holes
for enhanced bass.
The Nazarene Star is a
Dreadnought and the outside
dimension were religiously
followed but It has our
Sculptured Biplaner top with
our Almost Brace-less MMX
(Modernized Martin X) system.
It can be ordered with our
sculptured biplaner 2V2X
bracing system and epaulet
sound holes for enhanced
The traditional Martin X Braced type guitar because they do not use our Sub Structure
system have to brace the top very heavily above the sound hole to keep the neck from
caving-in the top and imploding rendering that area of the top mute except for very high
frequencies if at all?
The Nazarene Star (a Dreadnought) and
the Southern Star a (Southern Jumbo)
The Southern Belle is an OO
sized guitar It is smallest of our
steel-string guitars We built it
for smaller people and as a
platform for Tenor guitars and
five-string lead guitars Baritone
It body has the same
dimensions as our Der Hauser:
length 19 7/16" (493mm) upper
bout width 10 5/16" (278mm)
waist width 9 3/4 (247mm lower
bout width 14 3/8" (365mm)
depth at the neck block 3
10/16" (92.2mm) Depth at the
tail block 4 3/8" (111.7mm). It
has a tail block access panel
and an armrest.
The bass side hump on an El Conquistador is also quiescent because of sharp break at
the side junctions and the mass of the neck block. The neck block interferes with the van
Linge rings of activity so small sound holes on treble side of a size almost the same
thickness as the neck block allow the top to flex as if it had been thinned. The
bass-hump is a small quiescent area but still add to the volume of the guitar body and it
makes a great place for the largest of the sound holes without reducing the body volume
or interfering in the van Linge rings of top activity.
The Martin 'X' and our MMX places the center of the van Linge rings of activities at the
center of the 'X' intersection. To reinforced the monumental weakness induced by putting
a round sound hole between the neck block and the bridge it greatly defeats the van
Linge rings or activity above the sound hole that our 2V2X bracing of our tops do not do.
Our entire top takes place in sound production of our El Conquistadors using our 2V2X
tops except for their bass hump!
By using the 18th fret and carefully matching a scale to body we on the El
Conquistadors, can place the bridge exactly between the neck block and the tail block
allowing the maximum width of the van Linge rings of activities formations; allowing, the
fullest and the deepest bass sound possible without going to a round body guitar. You
can not get the fullness or the depth of sound that an El Conquistador will produce in
same size guitar!
We used to build an El Grande 24" X 18" X 7.5" The bass from one of those is!!!!
Our Classical guitars are individuals and are build with available materials all bindings are
wood. If you want something special order it!
Striped and fiddle back patterns in American black Walnut. Stika Spruce top
We offer 4-versions: a steel-six-string, a steel-seven-string, a steel-double-six-string, (it
uses two sets of six-string one medium gauge bronze and ultra light mono metal) and
other than the strings is identical to the steel-twelve-string offered.
The neck profile is narrower and shorter than Der Hauser with a fret scale of 22.7" and
the body/neck junction is at the 14th fret.
The Southern Belle can be ordered with our sculptured biplaner 2V2X bracing system
with epaulet sound holes for enhanced bass. It is available as a tenor guitar and a
double tenor. It is available in Mexican configurations as a 5-string lead guitar and
10-string with the same scale and neck/body junction.

The back is also sculptured of four laminations like our
successful Southern Star
It was surprising to us how small a dreadnought is! It is our
middle sized guitar which we religiously follow the Dreadnought
Fingerboard fret scale is 24.1" (612.1mm) with a body junction
at the 14th fret. The body size is: A Martin Dreadnought size
length 20” (508mm) width at the upper bout 11 1/8"; (281mm)
Waist 10 5/8" (270mm) width at the lower bout 15.6" (360.2mm)
depth at the neck block 3.88"; (98.5mm) depth at tail block
The back, sides and neck are of Padauk. The back is sculptured as well. It is the second
largest of our guitars and only slight larger but still with the appearance and size of a
Gibson Southern Jumbo or a J-45. Both are vintage guitars.
It is sometimes called a slumped shoulder Dreadnought because it is just a little bigger
than a Dreadnought.
Herman Hauser in His later guitars laminated the sides and his
backs with the inner layer of Spruce probably of local origin
Germany. Hemlock has been tested and found superior to Spruce
and less dense but in is unavailable and has other problems for
quality tops. I have found source of hemlock veneers that makes
great inner skins and cores.
El Conquistador is the largest of our guitars. It offer a
sound fullness unequaled and a playability only rivaled by
Der Hauser pictured has Engelmann Spruce (other woods are available) for the outer
skin, Nomex honeycomb core with lower skin of Hemlock. With carbon fiber bracing on
the underside of the outer skin and on underside of the lower skin. The top like most
classical guitars has a rigid dividing brace under the sound hole. The sides, back and
neck are of Paduak (other woods available).
The body dimensions are: length 493mm (19 7/16”) upper bout width 278mm (10 5/16")
waist width 247mm (9 3/4") lower bout width 365mm (14 3/8") depth neck block 92.2 mm
(3 10/16") depth at tail block 111.7mm (4 3/8") It has a tail block access panel, players
sound port, and an armrest.
