About This Listing

Boss OD-1 Overdrive in very good condition with JRC4558D op amp.
This Boss OD-1 comes with original box, which is a bit tacky.

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.

Version differences
The OD-1 has gone through a number of changes since its conseption. The different versions have been named OD-1A, OD-1B and so on. The version letter is printed on the PCB in the form of the number 052-281A to 052-281E. There are at least 4 different versions available. Each with minor differences like opamps from different manufacturers. The 4 digit serial number is ink stamped inside the battery compartment. These numbers are not real serial numbers but instead batch numbers. It is so far unknown how many pedals there were in a batch.
