A reliable pedalboard starts with clean power.
The MXR Iso-Brick is a compact, fully isolated power supply designed to keep your pedals running quietly and consistently, whether you're using a simple analogue setup or a more demanding digital rig.
Despite its small footprint, the Iso-Brick provides ten isolated outputs with a variety of voltage and current options to accommodate a wide range of pedals. Each output is individually isolated to help eliminate unwanted noise and ground loop issues, ensuring your signal remains clean from pedal to amp.
Two variable outputs allow voltages to be adjusted between 6V and 15V, making it possible to recreate the "sag" effect often associated with ageing batteries in vintage pedals.
Housed in a rugged metal enclosure, the Iso-Brick is built for regular gigging, rehearsals, and studio use while taking up minimal space on your pedalboard.

Why We Like It
The Iso-Brick strikes an excellent balance between size, flexibility, and reliability. It offers enough isolated outputs for most pedalboards while remaining compact enough to fit comfortably on smaller setups. For players looking for a straightforward, dependable power solution without unnecessary bulk, it remains one of the most practical options available.
