Pettyjohn ODI Classic / NOS

Not Like The Other 1.5
The ODi is based upon Stephen Pettyjohn’s own vintage BOSS OD-1.
The story goes, “Stephen’s first overdrive pedal back in high school was a 1978 Boss OD-1 and it served as his main overdrive for more than 10 years. He sold it when the prices for an original went sky high a few years ago but missing “that” sound he set out to recreate a pedal that captured the tonal characteristics that he loved about the original while adding the features he always wished he has on the original.”

Since the original was the worlds first true “overdrive” this is a modern classic.
Interestingly this pedal features Mods such as the Classic Mod featuring Two JRC4558 op-amps, full complement of vintage tone parts for the warmest, most vintage experience.
and the NOS Clipping Mod which adds the original New Old Stock (NOS) 1S1588 silicon diodes to the clipping section found in the earliest, most coveted OD-1 pedals.
We’ve also demo’s the pedal without these mods for you to compare!
