You know what the first user mod to this is likely to be? Especially organ players....

Paint the damn sliders the right color for Hammond drawbars

I find the brown black and white slider covers on the G70 of enormous value, not JUST to being able to grab the right drawbar for the organ, but also to guide your eye to the right slider for parameter adjustment, too. Nine identical sliders (and they still look pretty short throw to me) makes it tougher to find the right one in a hurry on a dark stage, IMO...
