As pedal boards grow, so does your need for more power! MXR's new Iso-Brick is small, compact, pedalboard friendly, and has 10 individual, isolated outputs for your pedal needs. Using only an 18 volt power adapter, you have two 9v 100ma, two 9v 300ma, two 9v 450ma, two 18v 250ma, and two variable outputs from 6v to 15v at 250ma to simulate voltage sag, much like a dying battery. this tiny thing can power a ton.
