AN EXAMPLE OF OBSESSION …..
While experimenting with different types of linings (often called kerfings) about a dozen years ago, I began making a hybrid lining with standard kerf cuts and reverse kerf cuts. It was surprising to notice an increase in sustain of the instrument with this hybrid lining. The increased glue surface of these hybrid linings was the suspected cause. To test this idea, linings were machined from solid Sapele stock. Again, there was an improvement in the sustain and the instrument had a more alluring tone. These solid linings require much more time to make and are not an efficient use of materials.
Now Charis linings are made by laminating veneer to the shape needed. This is a much more efficient use of materials, but it is even more labor intensive than machining them from solid stock! (Why do I make so much work for myself where folks rarely look!) These laminated linings are continuous from the head block to the tail block and are tucked into the head block, tail block, and cutaway reinforcement. The rims of the guitar are very ridged. They structurally support the top in a way that allows more control of the effects of bracing and top thickness.
An additional touch you will see on your Charis, is the wood buttons on the “Charis Acoustic” Gotoh 510 tuners. These buttons are made in the shop with woods complementing the wood choices in your instrument. The bridge pins are trimmed with dots made with woods to match, and a fine wood handle adorns the truss rod wrench. A fine instrument deserves nothing less.
