Power Your EMGs without a battery? Believe it!

I would be down for this kind of system on the fallowing way:

1. All of my pedals were also powered this way as well (so basically it appears as though you are running batterys, but instead you are using TRS cable from pedal to pedal to supply power).

2. It was a live rig. (I see no point in having this in a studio, but whatever).

3. Preferably the amp supplied the power so I didn't have to take that stupid box with me.

I mean it would be nice, no stupid power brick or other horse shit to plug in. Just connect your TRS cables and done. Think about it, you could have 12 pedals, a few powered guitars and all you have to do is plug in your amp to power them all.
 
From the manual:
"Using an AC Adapter is not a great idea. They tend to be noisy. EMG has yet to spec or design an AC Adapter. Effects pedals tend to be noisy because they usually add a lot of gain. Since the pickup is the first element of the chain it’s best for it to have as quiet a power supply as possible, thus a battery.
Both the ES-9 and ES-18 power supplies from EMG have inputs for Adapters. The choice is yours if you can tolerate any extra noise from an Adapter."
