ORIGINAL BOSS OD-1 OVERDRIVE EFFECT PEDAL
CIRCA 1981

The OD-1 is by now legendary. Artist of the 70's was mostly using a fuzz distortion sound and the overdrive produced by the OD-1 was not typical. It was however soon accepted as the new standard of guitar sound. The OD-1 features an asymmetric circuit where the positive and negative halves of the waveform isn't distorted equally. The sound is therefore still close to the original even though distortion have been added.
