Most IMPORTANT: “NEVER” Touch the “Attaching Surface”
Finger Oils & Soiling stops the AcoustaGrip from “clinging” to your instrument and may void your warranty! Hold Pad by the Sides Only (similar to a CD). Clean your instrument’s back (no polish or oils). After use, always replace the Protective Backing with the shiny side facing the “Attaching Surface” (Fig. 4). The enclosed Protective Backing Card is used for Storage or any time the shoulder rest is not attached to your instrument (shiny side attaches to the AcoustaGrip).
