Re: DC power adaptors: voltage too high – sorry about the typo’s – iPhone!

Theres an off-grid recording studio in Scotland which runs all of their equipment direct DC without any problems & I have hooked up my Zoom 707II guitar pedal, at 9v, directly to my batt-bank through an DC to DC reducer before & it still works just fine. Maybe making yourself up a secondary set of power cables for this stuff, just for low-voltage use would be benificial
