WNG Custom Damper Action

What Options Should I Choose? If you have any questions regarding what options to order with or how to order your damper action, please download the Custom Back Action Process instructions. You can specify a custom damper action by following these steps: 1) If you want WNG to supply damper heads and wires you will need to: - Establish the number of dampers in the piano. - Establish the number of bass dampers. 2) Determine which flange rail to use. 3) Determine Underlever Flange Types (with or without springs), Sostenuto Tab height, Spoon Length, and Leading Pattern.
