Mandolins

Designed for players who demand both subtlety and power, the ISI Mandolin brings our signature bowed-instrument craftsmanship to the mandolin family.

Each instrument is carved with precision—using the same plate-graduation, tone-bar voicing, and air-chamber tuning techniques that define ISI violins and cellos—to deliver exceptional nuance at amplified volumes without sacrificing acoustic warmth.

Available in all standard mandolin scale lengths and your choice of 8- or 10-string configurations, each ISI Mandolin features a hand-carved spruce top paired with back and sides in maple, rosewood, or walnut. Every instrument carries a lifetime warranty. Contact ISI for current pricing.
