This is a set including the main unit and cable. I am selling it because I am retiring from VOLTEX. I mainly played on AC, and I used this to practice charts rated 17 or lower. There is no box. The BT buttons have been modified for noise reduction and smoother operation. The plates inside the buttons have been removed and replaced with lightweight tissue. The Start and FX buttons have not been modified. I applied silicone spray near the springs when I noticed any spring noise. Operation has been confirmed. 【Product Specifications】 ・Buttons and Springs: DJDAO Buttons & 60g Springs ・Microswitches used for Start and BT buttons: Honeywell V15S05-EZ015-K01 15g ・Microswitches used for FX buttons: Honeywell V15S05-EZ015-K01 15g ・BT button light color: Blue (default) ・FX button light color: Red (default) SOUND VOLTEX SOUND VOLTEX FAUCE TWO GAMO2
