This little "Mate" sound post setter fits easily in a violin case compartment and is readily available for any adjustment work. The Post Mate is inexpensive, versatile and easy to use even by less experienced violin owners.
Optimal fitting and placement of the soundpost will make your instrument sound much better. Moving the post closer to the bridge usually produces more power, whereas moving the post away from the bridge will give less power and a form of richness. The tightness of the post also has an effect on the violin. A post that is set too tightly will choke the violin and require more bow pressure, whereas a loose soundpost will lack quality and be at risk for falling.
