Mastery MST String Tree
Available in-store only. We install for no additional charge with any setup!Mastery's string tree design is machined (not formed) and features our unique hard chrome plating so the strings glide smoothly without the use of moving parts. It has a little more break angle to prevent sympathetic overtones caused by low string tension and less surface area touching the string verses the 50s wing design. Comes with Mastery's custom stainless steel screw that's a bit longer as well as their custom made stainless steel spacer.
