The first instrument researched, designed, planned and built entirely from the ground up, and a return: a much smaller two-octave dulcimer was the first instrument I ever built, four years earlier, and started all of this.

This version carries a full 4.5-octave chromatic range, with extended bass notes below it, in a 19/18/6 course configuration. That range is the design problem: 204 individual string courses, 306 metres of string, and the tension they put into the frame, resolved through Canadian rock maple pinblocks, braces and bridges under a Honduran mahogany soundboard and back, trimmed in birdseye maple with blackwood rosettes.

It is fitted for the stage as well as the room: PUTW dual-element stereo transducer pickups into a K&K dual-channel Pro ST preamp.
