The BOSS Octave OC-2, a classic pedal for achieving a variety of octave effects. This unit has been modified for power and its sound has been confirmed. - Model: OC-2 - Brand: BOSS Thank you for viewing. I purchased this pedal myself and only used it for testing. It has never been used on stage and is a one-owner item. It has been stored in a rack in a warehouse for a long time. The exterior has no paint chips or scratches, and there is almost no sign of use. Of course, this is a used item, so please refrain from purchasing if you are concerned. Since it was battery-powered, there is no adapter. The power supply has been modified to confirm that it is working. (See photo 7) The sound has been confirmed. The thick sound of the old days has been revived. Please note that the ACA sticker remains. Type: Electric guitar, electric bass Manufacturer: BOSS There are no accessories, only the main unit shown in the photos. Please note that due to work commitments, it may take up to 5 days to ship the item.
