I've been using the OD-3 for a couple years now. I bought it because it didn't have that high-end raspyness that the BD-2 has (that I've used for years). I did a side by side test at the store between the two - big difference in smoothness. Overall volume gain was about the same.
I like the smooth overdrive of the OD-3, and it works great as a clean boost. The only thing I don't like about it (which I can overlook) is the db increase in the mid-range when it's on.
On it's own for overdrive, it's not extreme, and through a clean amp may not have enough od for some styles. For that, I still use my BD-2.
In comparison, I have an original OD-1 (japan) which sounds nothing like the OD-3. (OD-1 really thins out the sound when on).
