I have a Christopher DB302 that I am trying to optimize. After reading Traeger, I’m wondering whether a hardwood or better spruce soundpost would improve the instrument- he posits that hardwood matches the plywood’s impedance and better transers the vibrations.. I just found a setter that does not use a point, so can even try carbon fiber. (I have ww tools and know how to use them - just not as a paid professional.) I plan on trying several next week, but always value your experiences. 1. Has anyone experimented with hybrids? 2. With plywood, what soundpost materials have worked for you? 3, It still has the factory Christopher SPst, any thoughts on the quality? 4. Anyone played with carbon? Braided or composite? Tubular or solid? What do you do about fitting the ends if using tubular?
