This is a BOSS FOOT WAH pedal. Price negotiations are welcome. Since the operation of this item has not been confirmed, it will be treated as junk. It was working fine when it was last used about 5 years ago, so I am listing it at this price. Please understand that this is a junk item before purchasing. - Model Name: FOOT WAH - Input Terminals: INPUT - Output Terminals: OUTPUT - Power Switch: ON/OFF - Adjustment Knob: Volume Knob Thank you for viewing.
