Walter Martin – Sunhearth Instruments
Walter Martin (1911-1999) was a woodwork teacher and engineer from Roaring Springs, Pennsylvania. In 1970, Walt heard a dulcimer at a festival in State College, Pennsylvania, and felt an immediate attraction to it and its music. He had to have one, so he made it himself out of his grandmother’s walnut bedstead and some redwood he had lying around. It sounded so good he decided to make one for every member of the family. By then he just couldn’t let it go. He did some serious design research, and started taking the improved models around to craft fairs. His homestead (which he had designed and built himself) was called Sunhearth and that became the base for Sunhearth Folk Instruments in 1971. His designs were revolutionary for the time, with more volume, but also plenty of subtlety and great tone. Hi workmanship and attention to details was also legendary, with beautiful hand-carved scroll headstocks and tails. He attracted the interest of may big-name players of the time and Lorraine Lee Hammond in particular – with her wide range of music from blues, jazz to medieval – helped Walter develop his instruments. The top of the range model was the Concert Model. Walt made exactly 1000 appalachian dulcimers before retiring on his 80th birthday (1991). He also made some banjos and hammered dulcimers.

Handwritten in pen, inside far-side LB soundhole: “Sunhearth/ 981 – 28 – 91/ W. Martin”.
Big, fully bookmatched walnut body with three small feet. Beautiful fine-grained western red cedar top with Walter Martin’s trade mark four sun-shaped soundholes. Wide and deep hand-carved scroll/pegbox, fitted with gold Grover planetary tuners and custom walnut buttons. Odd, L-profile bone nut and bridge, with bone clamp to prevent string ring and stumpy copper string anchors also set in bone plinth. Bone fingerboard end and vent to body on tail. 6+, 13+ frets, no markers. Exquisite carved heel and tail. Designed for both conventional 3 string or 4 course equidistant string layouts, it was the classic instrument for players who favoured the extended harmonic potential of the latter. Dimensions of Standard model for comparison in []. Overall length 40½ [37]”, upper bout 5¾”, lower bout 7¾ [7]”, depth 2 [1⅞]”, FBW 1½”, VSL 27½” (medium scale), weight 2lb 08oz (1147g) [2lb 02oz (978g)], strings now 11, 14, 22w. 6+ and 13+ frets.
This has real presence, both in appearance and sound, the latter being full without being shouty, soft and sweet without being mushy and well balanced across the tonal range. Lovely action and tone, hence a delight to play – whether in three or four course form. The instrument is in generally fine shape, though the delicate red cedar top has a few scuffs along the edge and a short non-structural crack on the NS lower bout.
