I also tried the Fantom X knobs on the GW-7 and they work and look better. The tops are silver colored (matches the GW-7 color scheme) and there is a white indicator line on the bottom of the knobs, as well as a indentation on the silver top, which allow you to align things better. The knobs have a rubbery texture, are taller and have a nice taper, so it's easier to grab and turn...guess I'll be ordering 3 of these also!
