I've noticed some comments about the Mod Wheels being too bright. I LOVE my Mahogany Blue and while playing it, this wasn't a huge problem. But, when I'd step back to admire my beast, the Wheels were just too bright (and just didn't look good next to all my other synths lit up in a dark studio or even compared to the Moog's panel).
Now, (wish I could post anonymously for any warrantee voiding reasons

I accessed the Mod Wheel panel (two simple screws on the front) and found that each wheel has an LED that happened to be pointed right up at my eyes. I simply and gently bent the connectors on each LED so that the light pointed more downward. Carefull here: I'm sure they can't take much bending back and forth!
So, now the inside of my cabinet is bathed in a wonderful electric blue -- instead of my studio

Cheers!
