I'm not sure where you're getting stuck- but to Bypass, or Un-Bypass the pedal- you press the TWO pedals down at the same time.
To turn the Drums on, you press the DRUMS button on the pedal- pressing it again turns them off.
Not sure if that was all you were looking for, but if you are simply getting no signal to pas through the pedal, then please let me know what amp/mixer/recording console, etc. you are plugging it into and we can proceed.
The manual is also below if you do not have it:
Again, not sure if this is what you're asking- but anything else simply reply back here. We can go back and forth as needed until you've received the info you're looking for. Don't rate until you are satisfied.
Do you need any further assistance with this?
