The Gemini sound post setter tool is a dramatic improvement over the
traditional sound post setter design. Rather than piercing the sound post
with a sharp tip, our patent pending device holds the sound post securely against the saddle at the tip of the tool
without causing any damage to the sound post. This makes it easy to insert the sound post through the f-hole and into proper position without the risk of the sound post becoming dislodged as could happen with a traditional sound post tool. In addition, the fixed geometry of
the sound post and tool assembly allows you to precisely locate the sound post within the instrument. Finally, our unique release mechanism gently releases the tool from the sound post once it is in position.
This tool greatly benefits stringed instrument teachers because it allows them to quickly reset sound posts in student instruments, instead of sending them out for repair. This minimizes cost while maximizing practice time for the student.
The Gemini Sound Post Setter is a simple, easy to use tool for replacing or resetting the sound post in a stringed musical instrument. Below is a step by step pictorial description showing the proper use of the tool.
Step 1 Check to see that both
ends of the confiner line are threaded through the setter forming a loop around
the sound post saddle. Loosen the thumb screw to allow the line to move freely.
Step 2 Position the sound post in the cradle and hold it in position.
Step 3 Pull the line to tighten the line around the sound post and tighten the thumb screw snugly to hold it in place.
Step 4 Hold the sound post setter vertically over the instrument with the sound post over the setting location and the tube of the setter over the f-hole. Loosen the sound post slightly and rotate the sound post in the setter so the angles on the top and bottom match the curvature of the top and back. Re-tighten the sound post. Note the position of the setter as this will be the position you will match when setting the post.
Step 5 With the sound post now securely in the setter, carefully insert the sound post and setter through the f-hole and work the sound post into position holding it vertical and gently pulling the sound post towards you until you feel it wedge into position.
Step 6 When the sound post is securely in position between the top and back, loosen the thumb screw and capture one free end of the line. Gently remove the sound post setter from the instrument. One line will pull free from the setter and release the sound post.
Step 7 To re-thread the confiner line, loosen the thumb screw 2-3 turns. Hold the tube in a slightly downward position and thread the free end of the line into the empty hole and push through the body of the sound post setting tool.
