Hi to all. I'm new to the forum. I just got a "newish" spider valve 212 mk2 and it sounds good however I hear the treble randomly cutting in and out, like the sounds getting muffled intermittently. I also want to add that this also happens when I plug straight to the effects return. Any ideas are real welcome. Also, is there any authorized service centers in New Brunswick, Canada? Thanks, David
