So I just purchased Soul Bender, but I have no desire to power it using the adaptor plug (it's a center-positive pedal). I power my board with a Truetone 1Spot brick with isolated power. Could I use a Truetone reverse polarity cable? https://www.sweetwater.com/store/detail/1SpotCYR--truetone-1-spot-reverse-polarity-converter One of the reviews on that link says the guy tried it with the Soul Bender, but then the rest of his pedals didn't work. I'm assuming he was running a daisy chain and not a brick with isolated power, but I was hoping someone on here has had success with my intended approach. I'll just go with the 9V battery route if necessary.
