Soundpost Adjuster for Violin

This tool is specifically designed moving andsettinga sound post.The pointed end of the S-shaped setter is designed to pierce and position the sound-post inside the instrument and the other side is designed to pull or push in or out or tap from side to side.The position of the sound post inside a violin is critical, and moving it by very small amounts (as little as 0.5mm or 0.25mm, or less) can make a big difference in the tonal quality and volume of an instrument.

Soundpost adjustment is as much art as science. A good starting point for a sound-post is to have it a half thickness of the bridge behind the bridge towards the end-button also in line with the center of the E string side bridge foot. From this point, moving the sound-post closer to the bridge should increase the volume and brilliance of the sound while moving it away from the bridge should decrease the sound and less brilliance. Moving the post towards the f-hole/E string side, usually intensifies the higher register giving a brighter tone quality where as moving it away from the f-hole towards the center intensifies the lower register giving a darker tone quality.
