BOSS OC-2 ACA Specification Octave. I had this as a sub, but I'm selling it due to a change in equipment. Photo 8 shows a comparison between the Japanese and Taiwanese versions. (This listing is for the Taiwanese version.) The usage is almost the same. The op-amps are also the same, with only a difference in resistors. I compared the sounds, but I couldn't tell the difference. Operation has been confirmed with an adapter and batteries. Please use an ACA specification adapter for the adapter. Operation has been confirmed with a DC adapter and 9V batteries. Notes: Please take a close look at the photos and confirm any scratches or stains before making a purchase, and make your own judgment. Please refrain from purchasing if you are sensitive to these details. This is a used item that has been stored and used by an individual, so please refrain from bidding if you are looking for perfection. No returns or refunds. I am also listing this on other sites, so I may cancel the listing if it sells. Thank you for your understanding. #bossoc2 #bossoc #bossoctave #オクターバー (Octaver) #ボスオクターバー (Boss Octaver) #octaver Type: Electric Guitar Manufacturer: BOSS
