Multi-functional control panel for violin bass. These are parts I bought about three years ago as spares. I haven't installed them, so the functionality is unknown. I tried to replace the panel I have with the one in the fifth photo, but the screw positions were different. (The parts for sale are in the 1st to 4th photos.) I'm listing it because body modification would take time. When you search for "violin bass control panel" on online shopping sites, they are priced in the mid-3,000 yen range. These parts have become difficult to obtain. Get them while you can. - Type: Control Panel - Functions: Volume, Rhythm, Bass, Treble adjustment - Included: Mounting screws - Connection Type: Jack connection #ViolinBass #Hofner #ControlPanel Thank you for looking.
