    Product Description

    The MXR Iso-Brick Power Supply is small and light with tons of quiet, noise-free DC power on tap ready to run a wide range of pedal types without crowding or weighing down your pedalboard.

    Each of the Iso-Brick Power Supply's 10 outputs is fully isolated, eliminating gig-ending ground loop noise. Whether analog or digital, positive or negative ground, this power box has you covered. The MXR team broke down these 10 outputs to accommodate a variety of voltage and current requirements: two 9V outputs at 100mA, two 9V outputs at 300mA, two 9V outputs at 450mA, two 18V outputs at 250mA, and two variable outputs adjustable from 6V to 15V at 250mA. The two variable outputs can be used to emulate voltage "sag", a drained battery effect sought by many vintage tonechasers.

    On top of all that, the Iso-Brick Power Supply comes in a small, lightweight housing that’s built like a tank. Features power on/off and connection status LEDs. Put this little box on your pedalboard to make sure it runs reliably and quietly gig after gig.

    What is your opinion of this product?
    The first brand new unit had one of the 6-15V ports dysfunctional, but AMS replaced it (sending it by FedEx) pretty fast - in 2 days! The second unit now works flawlessly and the claimed voltages of each port are very accurate (within 3-9 mV from each claimed value), mostly slightly above the claimed voltage, although one 9V port consistently provides 8.97V. This is quite remarkable, because most Chinese-made power sources are almost invariably way off, for example, a putatively 12V DC power supply that came with the Tech 21 RK5 Multi-effects pedal consistently provides slightly over 22 V, which is 10 V above the claimed value! When using this original RK5's power source, I had to use a noise gate (MXR Smart Gate or TC Electronic Sentry) at higher gain settings of RK5's distortion. When using the MXR Iso-Brick, no noise gate is needed.
