I've heard this happen to other folks. I have both a Timefactor and Pitchfactor the and TF's power jack is fine but the PF's is loose – sometimes the unit will reset, as if I unplugged the power, when I engage a preset or accidentally graze the power cable with my hand. Sometimes when it resets, it will keep resetting in a loop – on/off, on/off, etc. until I hold the power cable a certain way.
I'm using a voodoo labs pedal power 2 plus to power both factor pedals.
