Update:
I just got a Timmy v2 and A/B'd it with the OD3. Both are supposed to be in the same non-TS/no mid-hump/transparent/low gain family.
Surprise surprise - the OD3 held its own! Sure, the Timmy was very versatile w/ its unique tone controls and selectable clipping circuit, but it had more gain than I expected! At 12 oclock it has more gain than the OD3 dimed. It also sounds grittier.
Anyway, I tried setting it at same gain level and eq and found the OD3 can retain quack and twang just as well as the Timmy. Whoa! But setting the Timmy's bass and treble full CCW (no cut) revealed it's still more transparent. And the Timmy's wide range of gain and tone just makes it really special and worth it. The Timmy's clean boost seemed cleaner and louder too.
In any case, both are keepers, probably the 2 best clean/transparent ODs I've had.
