Thank you for viewing. I created a control panel for a Jazz Bass using quilted maple. Currently, I am not producing these, so this is a limited-stock sale (3 remaining). Material thickness: Approximately 3mm Pot hole diameter: 9.8mm Screw diameter: 3.2mm (Screws are not included.) *Aluminum sheet is attached to the back for grounding. *Instant purchase without comment is possible, but excessive requests or significant price reductions are not possible. #control panel #control panel #jazz bass #electric bass #JB
