Hello,
It sounds to me like the thing you would want to do is put the TimeFactor out of Killdry and keep it out of the gigrig wetbox (and just keep the reverb in the wetbox.) That way the reverb level will remain the same regardless of your TF delay levels.
If you don't want to do that you may have to get another wetbox so you can have TimeFactor in one and reverb in another. (Or use a mixer with 2 aux sends.)
With the way you have it set now, the reverb level is going to depend on your Delay level, which is not what you would always want.
