Mastery String Tree MST
Brands:
Mastery's string tree design is machined (not formed) and features their 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 a custom stainless steel screw that's a bit longer as well as a custom made stainless steel spacer.
