Hand-painted and circuit bent Yamaha DD-7 drum machine with some tasty modifications  :D

Eight switches on the top panel, five of which are octave filters, the other three create different heavy, crunchy distortion effects

Eight buttons on the top panel cause the machine to glitch and spill out absolute madness, what seems to be every sound it knows.  Each button triggers different glitches, excellent for cacophonous fills

Eight buttons of the drums change the tones of the drums, adding crazy distortions, chopping up the sample. and/or whatever else the circuit feels like doing
