Atta boy, ya did good!
I like that the Gator supply has the three 18v outputs, but that feature doesn't leave enough room for an internal, ac supply, so you have to use a wall-wart. Also, the info doesn't say anything about the supplies being isolated.
VoodooLabs have a couple of power cables that have saved my ass:
Output Splitter Adapter - Ground Lifted. Allows you to run 2 9v pedals off of one output:
And, Voltage Doubler Adapter - 18V or 24V (runs the EPBooster and Treble Boosters @18v)
Voltage Doubler, thats a good one. Thanks!
