I bet this question has been asked before, but please be patient. I have a Holy Grail reverb. Not the original, not the neo or nano. This one has Electro-Harmonix on the bottom, and the
flerb. I want to power this unit with a voodoo labs iso 5 power supply. Is it possible to do this safely. I know that the manual says to only use the supplied power source. Has anyone used the iso 5 and the holy grail? If so, which power port ? Thank you.. I am new to this
