Hi folks,

I purchase the Pedal Power ISO-5 and MXR M300 reverb pedal. Upon setup it worked great. I recently got a new pedal board and set it up again. My reverb pedal would not power up. I switched the inputs from another pedal and the MXR worked for a moment and started to bling red and blue. I've sent a email to Dunlop asking what that is. I then connected it to a 12v input and it worked. Im worried that since this is a 9v it will ruin my pedal. Should I try and use the first 9v input on the chain or are there any suggestions? Thanks!

Sorry for the late reply here!

The M300 should be powered from the High Current 9V Output on the ISO-5. I would not use the 12V Output for this.

Let us know how it goes!
