This is the TRIAL Prime Chorus, a piece of equipment from Takahaya Gijutsu Gakki's brand, TRIAL. In addition to being able to create tones with SPEED and DEPTH, you can create a different kind of modulation by pressing the No-Vibe switch on the side. It seems to be modeled after the chorus of the JC-120. Production has ended, so it is expected to become difficult to obtain in the future. It was also one of my favorite pieces of equipment, but I will sell it to someone who needs it because I am purchasing other equipment. ○ Contents ・TRIAL Prime Chorus unit ・Box ・Instruction manual ・Rubber feet ○ Condition 　There are some fairly large scratches in several places. 　There are Velcro marks on the back.
