A 1987 Boss OD-2 Turbo Overdrive black label made in Japan serial (756500) Feb ’87. It has a nice thick overdrive with 2 channels and these have a much smoother tone than the reissues. It works 100% on both battery and ACA adapter, I can modify it for modern PSA 9 volt free of charge by request. It does not come with any box or accessories. It is in good condition with some wear and a few chips in the paint, see pics. The drive and channel select knobs have a gouge in the side.
