Charis Acoustic instruments are designed using both high and low tech methods. Computer aided modeling is used to help design the guitars and ensure all aspects of the instrument are addressed in terms of quality, and playability. A CNC Router is used to machine many of the guitar parts that must be duplicated with absolute precision. This process, in particular, is where Bill's engineering expertise, and the influence of his father's superior designing and machinist skills, are highly valuable to the overall process.

Though the CNC is extremely useful, the final touches are done by hand and by ear, to ensure every piece of wood is being used to its potential, and to test and measure the final results with an acute level of attention to every detail.

Rather than using the term "hand built", Bill prefers the term "personally crafted". Whether he makes a cut with a chisel or with a program he designs for the CNC, the final decision for where and how the cut needs to be performed, rests in his hands.

Bill chooses to use his passion, strengths and unique skills - whether by hand or with the computer - to create the most God honoring instruments that he possibly can. Based on client feedback and the smiles that appear when a Charis Acoustic is being played, his craftsmanship speaks for itself.
