BOSS Turbo Distortion DS-2 Made in Taiwan Functionality confirmed. Slight scratchiness present. Sound changes, so there's no problem. Remote operation not confirmed. Tested with my own AC adapter. Not tested with batteries. One screw missing from the back cover. Please understand that this is a used item before purchasing. #BOSS #DS_2 I apologize, but to avoid any trouble, I do not allow holds on any items I am selling. Also, due to work commitments, it may take a little time to ship. Thank you for your understanding.
