There is no point in just listing off the specifications to which I build my instruments. A design can be influenced by different sorts of wood and any number of parameters. There is enough freedom there. Creating THAT relies on conceptual decisions. The extra rigidity helps the sound to develop - the overtones harmonise better with all frequencies and have a stabilising influence.
Frequencies can either add together or, at the right moment, extinguish each other.
These Instruments possess enormous attack. This construction principle originates in traditional instrument making. A hollow instrument reverberates differently than one with a solid body. Today's music business demands highest performance from instruments, often in a difficult environment. An uncomplicated, easily processable, authentic acoustic sound is expected even under conditions where high temperatures, humidity and unpredictable changes of all kinds are the rule rather than the exception.
