The Jim Dunlop MXR Iso-Brick effect pedal power supply is a fully isolated box of juice that can power loads of different types of stompboxes! Rely on batteries no more, enjoy perfect, low noise power at all times! In a pedalboard friendly size you can mount it under a larger Pedal Train board or on top of pretty much any board. Whether you've got negative or positive polarity pedals, analogue, digital, this thing will power them all. 

Here's the power outputs you've got:

  • 2x 9v @ 100mA
  • 2x 9v @ 300mA
  • 2x 9v @ 450mA
  • 2x 18v @ 250mA
  • 2x variable outputs 6v - 15v @ 250mA

With the variable outputs you can even emulate the voltage sag effect or drained battery effect. When a pedal is plugged into the unit, an LED lights up, if it goes out it's much easier to troubleshoot where a potential problem is coming from - a very handy feature.

Overall, it's a fantastic power supply, if you've got some serious pedals then they deserve a great supply of juice and the MXR Iso Brick can give you what they need.
