This is a Line 6 FBV Shortboard MKII. As shown in the images, the power turns on and sound is produced, but the A, B, C, and D switching switches are malfunctioning. Also, one of the retaining tabs on the included LAN cable is broken. Therefore, I am selling this as a junk item, so would it be suitable for someone who can use it for parts or has the knowledge to repair it? The exterior has no major scratches and is clean as it has only been used indoors. - Model: FBV Shortboard MKII - Brand: Line 6 - Functions: Effect switches, volume pedal Thank you for looking.
