Info from Boss:
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.
