This is a Roland PSB-100 set, including the AC adapter PSB-1U and AC power cord. The output is center-negative 9V 2A. The power indicator lamp is the latest blue. After obtaining it, I rarely used it, so it's in good condition. However, the box has some creases. Compatible equipment includes Roland's CUBE Street, II, MOBILE CUBE, MICRO CUBE, and others. Shipping is included. It will be delivered via Yu-Packet Plus. Immediate purchase is welcome. I do not offer reservations, holds, or face-to-face transactions. Also, the person with the strongest intention to purchase will be given priority, even during negotiations. Shipping may take 1-2 days as it will be processed after work. Thank you for your consideration.
