I just received my HX Effects (purchased from Sweetwater) and I love it! I own two Godlyke Power-all PA-9D's - in a custom made pedalboard snake - neither of which will power on the unit. I am using the correct "cable green" (for Line 6) adapter. For reference... -The two Godlyke's (individually) will power on my M9. -The M9's power supply will power up the HX Effects Please tell us, if you used some magical version of the Godlyke power supply from the planet Asgard, let us know. Despite the power supply issue, I'm supremely happy with the HX Effects!
