everything works like it should except any distortion . metal . or any stompbox that has distortion i think there are 3 in my stompbox plug in all of them create a huge noise hiss and or loud background noise when activating the stomp box pedals . only distortion does this , all other effects are perfectly silent in function . i can use compression and or gate but still is not clear in recordings . gains do not help . drives do not help . amp modules are not the problem . it is possibly a update and or driver related issue ? i’ve tried everything i can think of , anyone have or had this issue?
