Overview

The MXR Iso-Brick Power Supply offers up 10 isolated outputs for a swath of voltages and power draws in a pedalboard-friendly size. This noise-free PSU is fully isolated, eliminating any worry you might have about cleanliness of the power in a venue or rehearsal space. With six 9V outputs (two at 100mA, two at 300mA, two at 450mA), two 18V 250mA outputs, and a pair of variable voltage outputs that swing from 6-15V, the Iso-Brick provides clean, safe power for all the pedals on your board...unless you've got more than ten.

    At first glance thus may seem a bit more humble than some of the more popular brands. But I’m here to say this thing is a good product. I run13 pedals with it and since there are 10 various isolated outs, you have to get up to speed with connecting 9V and 18V pedals. It’s important to note, the digi…

    I have read a lot of negative review (apparently, some people have experience failure, causing shorted-out pedals!). I have not experienced anything like that.
