OD-1 Over Drive (Silver Screw/Japan/RC3403ADB/#8000)

This is a rare, very early-production OD-1 featuring a Raytheon 3403 quad op-amp!!

Early OD-1 models featured a quad op-amp (a single chip containing four op-amps). While the RC3403ADB was used in the very earliest models and the NEC μPC4741C was used in units from lot #8400 to #8800, this unit features the former.The LED indicator is dedicated solely to the battery checker, differing from the specifications of the current BOSS Effector.Units equipped with the RC3403ADB are characterized by a somewhat tight low end, extended highs, and a bright, crunchy sound. This is a rare gem that lets you experience the original sound of the legendary OD-1!! This unit’s serial number is #8000, and it is believed to have been manufactured in March 1979.
