My favorite OD -- a ToneFactor Mule -- has a problem. It has one of those glaringly blue LEDs that seems designed to burn it's way through the back of my skull every time I look at my board. I can't even see the knob settings when I look down. I'm resigned to the steady hearing damage of playing electric guitar. To I have to put up with sight loss as well? So tell me. What are your ways of fighting the Blue Laser? Are they easily replaced? Etc., etc., etc.
