This is a vintage 1978 Boss Driver DB-5 electric guitar overdrive/boost/eq effects pedal by Roland. This particular example, serial number 622100, is in good all original condition. The pedal includes all (5) original white plastic switch tips, as well as, the original 9v battery door. The Boss Driver is a gain booster with a built in 5-band equalizer and compressor, which allows for the ability to completely sculpt and refine the nature of the pedal’s overdrive. Incredibly versatile, capable of producing piercing punctuation or a rich robust overdrive, this has become many pedal fanatics’ favorite studio secret.
