Yes – what often differs between pedals is the dispersion and component aging that changes the sound. Often there is also a bit of “voodoo”, that older devices are often supposed to sound better than newer productions. The fact is that the tolerances have become significantly better and tighter than in the 90s.
The current pedals (ODR-1 from 2020 with Bass Cut / ODR-1 Ltd and ODR-mini) can be operated with a DC voltage of 9-18 volts. Older ODR-1 without bass cut switch only from 9-12 volts DC.
Always pay attention to the polarity and voltage!
A higher operating voltage allows the sound to have a little more headroom and thus a little more transparency. This is of course a matter of taste and not always desirable. Even a very low voltage (dying battery) is sometimes appealing. Here you get almost sounds like a FUZZ.
Many popular overdrives used a simple adjustable filter for the high frequencies. It was called “Tone” or “Treble” and really just reduced the high frequencies added by the overdrive electronics. Of course, this greatly limits the variety of sounds and possibilities.
After much sound testing, Kai Tachibana developed what was then, and we still believe, the unique double filter control called “Spectrum”. Not only the usual highs are raised or lowered, but also the lower mids/bass (~300 Hz). In the 12 o’clock position the sound is almost neutral. Turning the control counter-clockwise minimizes the treble and bass. Raised clockwise.
This allows a variety of EQ settings with just one knob.
The ODR-mini a little bit tighter than is big brother and have a different frequency range in the bass.
But the DNA is the same and the basic sound very close.
