The MXR DC Brick power supply is the perfect way to power your midsize guitar or bass pedalboard. The simple and compact DC Brick power supply provides enough power for 10 of your favorite stompboxes, without hogging your pedalboard. Eight 9V outputs and two additional 18V outs provides clean power to each of your pedals, without the sag and starvation you get with a budget system. There are even LEDs onboard the DC Brick, which warn you in there's a short on the line.
