I've been working with one of my tskedowns to get it quieter. I've played with brace height, arrow selection, put wool string silencers on the strings and wrapped the string ends with wool (Bow Hush) style. Everything is pretty good except for a low "thrumming" sound. I can get the sound just by plucking the string a little bit. I know something is still vibrating so I've tried gripping the string, and gripping the limbs. Gripping limbs kills the sound immediately. What is the best way to get rid of some limb viration? Should I try limbsavers? If so, how do I choose the best placement before finally attaching them? Any advice would be greatly appreciated.
