This is a TK mod for the BOSS LS-2. It has the same modifications as those done for TK of the band Ling tosite sigure. I purchased it new in October 2019 and had it modified by SPI in June 2020. I have confirmed that it works with both an adapter and batteries. It comes with the original box and accessories, which you can see in the photos. Please note that I am not accepting price negotiations. Thank you.
