<span style=”font-size: inherit;”>I’ve been having problems with pitched noise when I insert pedals into the H90’s send/return. I currently use a IK ToneX Pedal and a Jackson Audio Broken Arrow(high-gain signal), or even-clean amp simulation along with the H90’s WeedWacker algorithm, pitch noise occurs. What confuses me is that when I isolate the H90 and use ToneX’s output for a PA or audio interface, the noise doesn’t occur. I think this issue must be related to the H90’s input/ output gain levels. Are there any usage restrictions or specific settings that I should be aware of? The H90 is being used with a factory power supply, and the other pedals are connected to a good-quality isolation power supply. I also check the connection cable, and there was no change in the scenario.</span>
