I have a little Mesa amp that came with a "Switch Doctor" footswitch. Three switches and three LEDs that are retina-searing bright when compared to the LEDs on my pedals. I don't absolutely need the footswitch but it's handy and I'd rather keep it. Any way to reduce the brightness of the LEDs? I was musing first about just putting some artful beige masking tape over them, then started thinking about whether a simple internal mod might tone them down.
