Hello,

I purchased the Holiest Grail a few months ago. On my guitar pedal effects board it works really well with a clean signal and no distortion. When I use a Tube Screamer I get a bad background noise that is sometimes very noticeable. When i use a fuzz pedal it really screams out. Is there any way to fix this? Is it a problem with the pedal? What is the best position for the pedal on a FX board? Please help.
