Thank you for viewing. I created a control panel for a jazz bass using flame maple. This is the last one available as I am no longer producing them. Material thickness: Approximately 3mm Pot hole diameter: 9.8mm Screw diameter: 3.2mm *Aluminum sheet is attached to the back for grounding. *Discounts are not available for single items, but a set discount (300 yen off) is possible when purchased with other items, so please feel free to inquire. #control panel #control panel #jazz bass #electric bass #JB #B
