This is a BOSS Blues Driver. It's famous for being used by Washiyama of Suspended 4th and Tabuchi, formerly of NUMBER GIRL. The serial number has been removed, making it difficult to pinpoint the exact year of production. Based on the features, such as the lack of a CE mark and the reddish discoloration around the edges (as seen in the 4th photo), it's likely an early model. Furthermore, the circuit board is dark brown (photos 9 and 10), and the tantalum capacitors are the blue C22 and C24, which are also characteristics of early models. The op-amp appears to be a Mitsubishi M5218AL, although it may not be clearly visible in the photo. Based on the above, I believe this is an early model from around 1995. Please refrain from purchasing if you are particular about details or if the absence of a serial number is a concern. It has some scratches and wear commensurate with its age, so I'd like to sell it to someone who doesn't mind those things. There are no boxes or accessories. Please note that this item is also listed on other sites. Type: Electric Guitar Manufacturer: BOSS
