Power for the Eventide H90
The 1 A is the rating on its adapter, not a measured draw.
We have no measured draw for it. Give it the adapter it came with, or an output rated 1 A or more at 12 V.
Warning. The Eventide H90 is center-positive. Most pedal supplies are center-negative, and plugging it into one can damage it. Use a supply that states a center-positive output.
