◆ BOSS CS-2 Compression Sustainer for sale. ・Serial: 486600 ・Made in Japan, Black Label ・Estimated year based on serial number: November 1984 ・Functionality confirmed (operates normally with DC cable and 9V battery) ・Each knob functions, with no noticeable crackling or noise. ・The appearance is also good, and I think it's in the category of a beautiful item considering its age. ・The rubber rings on the screw receivers have deteriorated over time. Please be aware of this. This is a popular model known as a legendary compressor, with the appeal of a natural compression and extended sustain. It is still used by many people and is recommended for both collection and practical use. Looking at used ones on the market, many have unclear or peeled-off black labels on the back, and many are not in good condition, but this unit is in very good condition. It has been used sparingly and has been carefully stored in a long-term equipment storage. As shown in the attached photos, I think it maintains a very good condition considering it is a vintage item. No accessories, only the main unit is for sale. ※ In my opinion, I think it is a unit in good condition, but please consider it as a used item. ※ Since there is no BOSS genuine ACA adapter, the operation with an ACA adapter has not been confirmed. ※ The description is based on what is estimated from the serial number and label. There may be errors in the content or description. If you have any questions, please feel free to ask before purchasing.
