PRODUCT TECHNOLOGY
The square-shaped ISOMETRIC frame shape is designed to keep vertical strings at a similar length, as well as the horizontal strings to produce an expanded sweet spot in all directions.

Muscle Power locates the string on rounded archways that eliminate stress-load and fatigue through contact friction. This construction creates total unity of the string and frame through closer and tighter contact.
