100V specification. Firmware updated to Ver4. This unit is in good condition for its age. No returns or exchanges. The following maintenance has been performed: ・Full overhaul by a former craftsman of the vintage instrument company, FiveG, resulting in a masterpiece. ・POT cleaning and replacement of faulty switches. It features a very powerful and punchy sound. Although many sampling and clone sound sources are available, if you want the original sound, it's best to buy the original. Thank you for viewing.
