As far as I understand it, all the eventides actually draw somewhere in the neighborhood of 350mA at 9 volts so the 400mA / 9v supplies suffice. The Voodoo Lab website / video says it can power 4 eventides. Here's a video of a timefactor having its current measured at 9 volts. http://www.youtube.com/watch?v=lkISu3NBRH4&feature=youtube_gdata_player
