For the top bracing pattern, we use Scalloped X bracing for “Luthier Made” models, Scalloped XX Bracing for “Hand Made” models and Classical Lattise Bracing for the new SJ-171 model. In addition, we curved out both sides of the X bracings and one side of the XX bracings to help distribute the vibration of the strings from the bridge to the top more evenly, and produce rich sounds which sustain high to low notes. Also, both models employ “X Bracing” to the back. “X bracing” the back will allow it to vibrate like the top and create a richer, more rounded sound.
In order to transmit sound effectively and prevent movement of the neck, we joined the body and neck with a tightly fit dove tail. We also set the neck at a shaper angle so we can keep a comfortable low action, even at the higher positions.
We only use carefully selected, naturally seasoned wood. The outer area of the top, where the top is attached to the rim, is sanded thinner than the center. All of the parts are secured tightly using a specially formulated glue, which produces a result close to the hide glue. Grand Auditorium, Classical Auditorium and Semi-Jumbo all have a smaller size body, but we increased the depth of the body to obtain a big sound. For the back we offer “Flat Back”which has a light arch from the bass side to treble side. “Round Back”has dish-like shape, arched on both the bass side and treble side from the heel to the bottom. Both models have a wonderful tone and sustain, but “Round Back” will emphasize more overtones and give a powerful bass, increased volume and sustain. All of the models have either Venetian Cutaway or Florentine Cutaway.
To be able to fret the 6th string easily with the thumb, while allowing extra space for the 1st string to prevent the string from falling off the edge of the fingerboard, we moved the strings approx. 0.04 inch (1 mm) to the left, without changing the actual string spacing.
In order to provide the most comfortable playing environment on the fingerboard, we made a slightly wider fingerboard with 1.73~1.77 inches (44~45mm) at the nut and 2.17~2.20 inches (55~56mm) at the 12th fret, gave a slight arch (300R) to the surface, and fretted precisely with thinner and harder frets.
