BOSS BD-2 Blues Driver The pedal turns on normally with both battery and power supply. However, when I add gain/drive, I think it's making a strange sound that isn't the pedal's normal tone. Because of this, I'm listing the pedal as junk. For the same reason, I'm selling it at a price lower than the market price. Please check the condition in the photos. Velcro is attached to the back, so it can be easily installed on a pedalboard. Please refrain from purchasing if you are not familiar with used items, if you are looking for perfection, or if you are overly concerned about details. Please use NCNR (No Claims, No Returns). Thank you for your continued support. Manufacturer...BOSS
