Selling the legendary Boss NF-1 noise gate pedal from the late 1970s and early 1980s. As part of the first and most famous Black Label era, this is a rare "silver screw / long dash" version from the early years of production. Unfortunately, the serial number has not been preserved; however, in this configuration, the pedal was manufactured only in 1979 and through part of 1980, following its introduction in 1979. The pedal is in very good and attractive condition; everything works as it should. Virtually no cosmetic flaws. Powered by ACA (a standard 12V DC adapter can be used) or a 9V battery.
