This is the BOSS (Roland) AC adapter "ACA-100G". I am selling it to organize my equipment. This is an "ACA" specification adapter, which is compatible with older BOSS compact effects pedals, rather than the current mainstream PSA adapter. It is a rare, made-in-Japan model. 【Condition】 This is a used item. There are scratches and wear on the label due to aging, but there are no major tears in the cable insulation. I have confirmed that it powers on and works with my BOSS Metal Zone. It was able to supply power without any problems. 【Product Details】 ・Manufacturer: BOSS (Roland Corporation) ・Model Number: ACA-100G ・Input: AC100V 50-60Hz ・Output: DC 9V 200mA ・Country of Manufacture: Made in Japan 【Please Note】 This is an "ACA" type adapter. It is ideal for old Japanese and early Taiwanese BOSS effects pedals (ACA specification). Using it with current "PSA" designated digital effects pedals may cause noise or malfunction. Please check the specifications of your equipment before purchasing. Thank you for your consideration. #BOSS #Boss #Roland #Roland #EffectsPedal #ACAdapter #ACA100G #MadeInJapan #Vintage #Guitar #Bass #MetalZone
