When installing Graph Tech saddles or nuts, replace any retainers (string trees) with TREM-NUT string retainers to alleviate friction and binding at these contact points.
TREM-NUTS alleviate the binding grip of the nut on the string and reducing friction between the nut material and the string. This is accomplished using a nut manufactured from an engineered resonant base material impregnated with Teflon.
