Have any of you had a popping or crackling sound come from your attenuator? I just installed my GP attenuator and when I cycle back from click 17 to 16 I get a light pop or click in the right channel. When I go from 16 to 17 nothing, but from 16 to 17 I get a pop. If I try and move it real slow it sounds like a louder pop or crackle only on the way back from 17 to 16. I plan on calling G0oldpoint but thought I would check in here to see if you guys had any suggestions.
