This is a modification of a DS-2, famous for being used by John Frusciante and Kurt Cobain, with parts replaced. The modification pushes a roaring, fuzzy band of frequencies. I took pictures of the inside, so please check them if you are familiar with parts. The box is included. Although I don't know the detailed MOD contents, ・The LED has been replaced with a blue one. ・Some parts have been changed (see image 2). ・It turns on automatically when the power is turned on. etc. have been changed. Regarding the sound, I don't have the original before modification, so my impression is based on watching a demo video, but I felt that the gain has increased considerably and it sounds like a fuzz.
