Reply To: UltraTap causing noise with pedal board power supply

So the H90 and UltraTap does not use a wall wart and has a mains AC IEC plug that attaches to the device? A wall wart is not a built in PSU. Also, many wall wart devices are not switching. I’m willing to bet the H90 is not. The H9 was not.
