Gretsch's Tom suspension system allows rack and floor toms to freely suspend on mounts without any direct contact to the shell. The rubber grommets that sits between the bottom of the counter hoop and the Gretsch lug won't create any tension or scratch your drum. A G9025 Hinged Bracket attaches to the GTS Engraved frame allowing you to fasten your toms to a 12.7mm post. The GTS system is Gretsch's standard build option for all Gretsch USA Rack and floor tom new builds. It's also available as an aftermarket sales part.
