Alright, so I'm starting to build a collection of pedals. Not many, 4 or 5. I got a Fulldrive 2, Phase 90, tuner, and a delay. I have to use 9Vs on all of them. I know that that will begin to add up for the prices of the batteries. I've been doing some research on pedal power bricks, and the Voodoo Pedal Power has been the most recommended one. Now I'm new to this because I've always used batteries. My question is, will I only need one adapter for one of the pedals and just use coupler cables to run off the one with the adapter? Or will I need 9V adapters for ALL the pedals and they all plug into the pedal power?
