i listened the sound samples, it says "Odie bypassed, then active"...

I'd say that bypassed means off and active means on.

That's more than likely what they mean.

is that all?
bypassed means swithched off the pedal...
so will pedal still affect my sound or totally ineffectibe?

if it is a true bypass it usually just connects the two jacks together so shouldnt affect your tone at all
