I have a new pedal board set up and I'm using the power factor. I have 3 eventides already but I got a MIDI mastermind on board too I need to power. It takes 9V-18V @200mA but it does work on one of the 9V 80mA inputs. The problem is, when I plug in an expression pedal, it doesn't have enough juice to run it and powers off intermittently. I heard I can chain 2x 9V @80mA – will this work, or will it screw my Mastermind. Ideally I wish I had 1 more 12V because it works perfect on those ones. Cheers.
